User: To solve for y in the equation 2x + y = 5, subtract 2 from both sides of the equation.

User: Solve 3x - 5 + x = 31. -12 -9 9 12

Weegy: 3x - 5 + x = 31

3x + x = 31 + 5;

4x = 36;

x = 36/4;

x = 18

User: Kobe's overtime pay is \$5 an hour more than his regular pay. He worked 8 hours at his regular wage and 3 hours at his overtime wage. He earned \$114. What is Kobe's regular wage per hour? \$5 per hour \$9 per hour \$14 per hour \$23 per hour

Weegy: Kobe's regular wager per hour is \$12.375. Equation 114=(x*8)+(3*5) makes it to 114-15=8x.x being the regular pay = 99/8 = 12.375

User: Solve -(2x + 4) = 18. -11 -7 7 11

Weegy: |2x - 5| = 4;

-(2x - 5) = 4; -2x + 5 = 4; -2x = 4 - 5; -2x = -1; x = 1/2
- - -
(2x - 5) = 4; 2x = 4 + 5; 2x = 9; x = 9/2,

x = 1/2 or x = 9/2

User: Solve the following equation, explaining what you did in each step of your solution. After solving the equation, show the steps to check your solution. 3x + 2(4 + 6x) = 113

Weegy: 3x + 2(4 + 6x) = 113
Simplify: 2(4 + 6x) = 8 + 12x;
Combine like terms: 3x + 8 + 12x = 113; 15x + 8 = 113;
Add -8 on both sides: 15x + 8 - 8 = 113 - 8; 15x = 105;
Divide both sides by 15: 15x/15 = 105/15; x = 7
Solution is x = 7

To check, substitute x to 7:
15(7) + 8 = 113;
105 + 8 = 113;
113 = 113

User: The sum of four consecutive integers is 74. What is the first integer? 16 17 18 19

User: 9x 2 and 5x are like terms. True False

Weegy: x = 3/4

User: 9x 2 and 5x are like terms.

Weegy: (2x^2 - 3x^3) - (5x^2 - 9x^3)

= 2x^2 - 3x^3 - 5x^2 + 9x^3

= (- 3x^3 + 9x^3) + (2x^2 - 5x^2)

= 6x^3 - 3x^2

User: Simplify 8(x - 4). 8x - 4 x - 32 8x - 32 x - 4

User: Simplify 3x + 6x 2 - 5x - x 2

User: Simplify 3x + 6x ^2 - 5x - x ^2

Weegy: (8x - 12)/(2x^3 - 3x^2)
= 4(2x - 3)/x^2(2x - 3)
= 4/x^2
