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 )
- = x ← is the solution
