Answer:
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.
