3x = 46
x = 15.333...

• The did not distribute correctly
• They did not add correctly
• They did not divide correctly
• They did not subtract correctly

Solve:
2x - 5 = -3x - 35

• x= -7
• x= -6
• x= -2
• x= 5

What property justifies step 1?
Problem: 2(x + 3) = 12
Step 1: 2x + 6 = 12
Step 2: 2x = 6
Step 3: x = 3
