5x+7=-14+8x what is the value of x

x = 7

Step-by-step explanation:

5x + 21 = 8x

21 = 3x

7 = x

X=7

Step-by-step explanation:

To solve this problem, first, you have to isolate it on one side of the equation. Remember to solve this problem, isolate x on one side of the equation.

5x+7-7=-14+8x-7 (First, subtract 7 from both sides.)

-14-7 (Solve.)

-14-7=-21

5x=8x-21

5x-8x=8x-21-8x (Next, subtract 8x from both sides.)

5x-8x (Solve.)

5x-8x=-3x

-3x=-21

-3x/-3=-21/-3 (Then, divide by - 3 from both sides.)

-21/-3 (Solve.)

-21/-3=7

x=7

Therefore, the correct answer is x=7.
