User: what equation could be used to solve the equation 1 + 3x = -x + 4

User: Select steps that could be used to solve the equation 1 + 3x = -x + 4.

User: If the first step in the solution of the equation 2x - 8 = 5x + 3 is "subtract 2x," then what should the next step be?

Weegy: -8 = 3x + 3, therefore you subtract 3.

User: If the first step in the solution of the equation -9 + x = 5x - 7 is "subtract x," then what should the next step be?

Weegy: -9+x=5x-7 Since 5x contains the variable to solve for, move it to the left-hand side of the equation by subtracting 5x from both sides. x-9-5x=-7 Since x and -5x are like terms, [ add -5x to x to get -4x. -4x-9=-7 Since -9 does not contain the variable to solve for, move it to the right-hand side of the equation by adding 9 to both sides. -4x=9-7 Subtract 7 from 9 to get 2. -4x=2 Divide each term in the equation by -4. -(4x)/(-4)=(2)/(-4) Simplify the left-hand side of the equation by canceling the common factors. x=(2)/(-4) Simplify the right-hand side of the equation by simplifying each term. x=-(1)/(2) ]

User: Solve for x. 16x - 5 = 18x - 2

Weegy: x = -1 1/2

User: Solve for x. 15x + 6 = 10x + 21

Weegy: 15x + 6 = 10x + 21, 15x - 10x = 21 - 6, 5x = 15, the result is x = 3

User: Solve for x. 7x - 3/8 = 6x - 5/8

Weegy: 7x + 7 + 6x - 9

7x+ 6x+7 - 9

13x-2


User: what is x in the equation 7x - 3/8 = 6x - 5/8

Weegy: Simplifying 4 + -7x + 10 = 15 + -6x + -8 Reorder the terms: 4 + 10 + -7x = 15 + -6x + -8 Combine like terms: 4 + 10 = 14 14 + -7x = 15 + -6x + -8 Reorder the terms: 14 + -7x = 15 + -8 + -6x Combine like terms: 15 + -8 = 7 14 + -7x = 7 + [ -6x Solving 14 + -7x = 7 + -6x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '6x' to each side of the equation. 14 + -7x + 6x = 7 + -6x + 6x Combine like terms: -7x + 6x = -1x 14 + -1x = 7 + -6x + 6x Combine like terms: -6x + 6x = 0 14 + -1x = 7 + 0 14 + -1x = 7 Add '-14' to each side of the equation. 14 + -14 + -1x = 7 + -14 Combine like terms: 14 + -14 = 0 0 + -1x = 7 + -14 -1x = 7 + -14 Combine like terms: 7 + -14 = -7 -1x = -7 Divide each side by '-1'. x = 7 Simplifying x = 7 ]

User: Solve for x. 13x + 7 = 5x - 20

Weegy: x=3 (which would make it 15 + 0 = 15)

User: Solve for y. 7y - 6y - 10 = 13

Weegy: 7y - 6y - 10 = 13,

y = 13 + 10,

y = 23


User: If an equation is an identity, then how many solutions does it have?

Weegy: If it's an identity over an infinite field, then it has an infinite number of solutions. Example: sin?x + cos?x = 1 is true for all x. source:yahoo

User: Which of the following equations has the solution set {0}? -14m - 7m + 1 = -7m + 1. -14m + 7m + 1 = -7m + 2. 14m - 7m - 1 = -7m + 1.

Weegy: A.-14m - 7m + 1 = -7m + 1

debnjerry|Points 44902|

User: Which of the following equations are equivalent to -2m - 5m - 8 = 3 + (-7) + m? -15m = -4m -7m - 8 = m - 4 -3m - 8 = 4 - m m - 4 = -7m - 8 -8 - 7m = -4 + m -8 - 3m = 4 - m

Weegy: -15M = -4M -7M -8M

18 - 3n + 2 = n + 20 - 4n
20 - 3n = 20 - 3n
-3n + 3n = 20 - 20
0 = 0
Therefore, the solution set of 18 - 3n + 2 = n + 20 - 4n is all reals

7 + x - 15 = -2 2/3
x - 8 = - 8/3
x = 8 - (8/3) = 24/3 - (8/3) = 16/3
