Jonathan was simplifying the expression shown for homework but made a mistake.
Given: 3(4x+6y) (8x + 20)
Line 1: 12x + 6y-2x-5
Line 2: 10x + 6y - 5
Line 3: 2(5x + 3y)-5
Which statement describes how Jonathan should fix his first mistake?
1. On line 1, subtract 5 should be add 5.
2. On line 1, 6y should be 18y.
3. On line 2, 10x should be 14x.
4. On line 2, 6y should be y.
