Answer 1

Answer:

see explanation

Step-by-step explanation:

32 - 7x = 2x - 3(4x - 5) ← distribute parenthesis

32 - 7x = 2x - 12x + 15

32 - 7x = - 10x + 15  ( add 7x to both sides )

Anna made her error here in that she subtracted 7x from both sides

32 = - 3x + 15 ( subtract 15 from both sides )

17 = - 3x ( divide both sides by - 3 )

- $\frac{17}{3}$ = x ← is the solution
