Answer:
23+7-2x=8x
We simplify the equation to the form, which is simple to understand
We move all terms containing x to the left and all other terms to the right.
-2x-8x=-23-7
We simplify left and right side of the equation.
-10x=-30
We divide both sides of the equation by -10 to get x.
x=3
Step-by-step explanation:
23 +7-2x=8x
Combine like terms
30-2x=8x
Add 2x to each side
30-2x+2x = 8x+2x
30 = 10x
Divide each side by 10
30/10 = 10x/10
3 = x
