Question

The solution to the equation 4(x – 7) = 64 is shown. Which step is a result of combining like terms?

A) Step 2
B) Step 3
C) Step 4
D) Step 5

Answer 1

Step 3 we're adding 28 to both sides which leads to step 4, where we are combining like terms. On the left side -28+28 turns into 0 and effectively goes away. On the right side 64+28 becomes 92

Answer: C) step 4
