Unit 1 Getting Ready

Sarah incorrectly solved the equation $-6\left(7n+7\right)=-294$  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
