Sarah incorrectly solved the equation -6(7n+7)=-294 as shown.

Step 1:      -6(7n + 7) = -294
Step 2:       -42n - 42 = -294
Step 3:               -42n = -336
Step 4:                n = 8
Between which two steps did Sarah make a mistake?

• Step 1 and Step 2

• Step 2 and Step 3

• Step 3 and Step 4

Peter incorrectly solved the equation 86=-5(-6+2x)+3x as shown.

Step 1:     86 = -5(-6 + 2x) + 3x
Step 2:      86 = 30 + 10x + 3x
Step 3:     86 = 30 + 13x
Step 4:     56 = 13x
Step 5:      4.3 = x
