Question

Explain how to do this problem in steps and include answers as well

Answer 1

$8(4x-5)-12=20x-10\\ 32x-40-12=20x-10\\ 12x=42\\ x=\frac{42}{12}=\frac{7}{2}$

Answer 2

$8(4x - 5)-12=20x-10$

$32x - 40-12=20x-10$

$32x -52=20x-10$

$32x -52 -20x=-10$

$12x -52=-10$

$12x =-10 +52$

$12x =42$

$x= \frac{42}{12}$

$x = \frac{7}{2}$

$x=3 \frac{1}{2}$  ≈ 3.5
