We replace y (= 4 + 1/3x) in the equation -1/3x + y = –1 we can get

-1/3x + 4 + 1/3x = –1

Simplify the equation we get 5 = 0

We all know that 5 could never be equal to 0

That is to say, there is no solution for -1/3x + y = –1 and y = 4 + 1/3x

-1/3x + 4 + 1/3x = –1

Simplify the equation we get 5 = 0

We all know that 5 could never be equal to 0

That is to say, there is no solution for -1/3x + y = –1 and y = 4 + 1/3x

Solve the equation.
6 = 2(x + 8) - 5x
A. 2/3
B. 3 1/3
C. - 2/3
D. -3 1/3 **Weegy:** -3 -3
Divide each term in the inequality by 3.
(3(5x-16))/(3)>-(3)/(3)
Simplify the left-hand side of the inequality by canceling the common factors.
5x-16>-(3)/(3)
Simplify the right-hand side of the inequality by simplifying each [ term.
5x-16>-1
Since -16 does not contain the variable to solve for, move it to the right-hand side of the inequality by adding 16 to both sides.
5x>16-1
Subtract 1 from 16 to get 15.
5x>15
Divide each term in the inequality by 5.
(5x)/(5)>(15)/(5)
Simplify the left-hand side of the inequality by canceling the common factors.
x>(15)/(5)
Simplify the right-hand side of the inequality by simplifying each term.
x>3
c. x > 3 is the answer. ] **User:** Solve the equation.
x - 9 = -6x + 5
A. 14
B. 7
C. 2
D. 21 **Weegy:** The answer is x=2. (More)

6 = 2(x + 8) - 5x

6 = 2x + 16 - 5x

3x = 16- 6 = 10

x = 10/3 = 3 1/3

The solution for the equation 6 = 2(x + 8) - 5x is B. 3 1/3

6 = 2x + 16 - 5x

3x = 16- 6 = 10

x = 10/3 = 3 1/3

The solution for the equation 6 = 2(x + 8) - 5x is B. 3 1/3

x - 9 = -6x + 5

x + 6x = 5 + 9

7x = 14

x = 14/7 = 2

The solution for the equation. x - 9 = -6x + 5 is C. 2

x + 6x = 5 + 9

7x = 14

x = 14/7 = 2

The solution for the equation. x - 9 = -6x + 5 is C. 2

The answer for the equation x/5 + 9 = 4 is -25.

x/5+9=4

x/5=4-9

x/5=-5

x=-25.

x/5+9=4

x/5=4-9

x/5=-5

x=-25.

2(x + 4) = 30

x + 4 = 15

x = 15 - 4

x = 11

x + 4 = 15

x = 15 - 4

x = 11
