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

Answer:
x = 2
Step-by-step explanation:
x + 1/2 (6x - 4) = 6
Expand the brackets.
x + 3x - 2 = 6
Add like terms.
4x - 2 = 6
Add 2 on both sides.
4x = 6 + 2
4x = 8
Divide 4 into both sides.
x = 8/4
x = 2
