Answer:
(D) 21
Explanation:
3(2x−1)−10=8+5x
Step 1: Simplify both sides of the equation.
3(2x−1)−10=8+5x
(3)(2x)+(3)(−1)+−10=8+5x(Distribute)
6x+−3+−10=8+5x
(6x)+(−3+−10)=5x+8(Combine Like Terms)
6x+−13=5x+8
6x−13=5x+8
Step 2: Subtract 5x from both sides.
6x−13−5x=5x+8−5x
x−13=8
Step 3: Add 13 to both sides.
x−13+13=8+13
x=21
