Question

21.

Teddy incorrectly solved the equation 3 - (x - 1) = 2(x + 3) using
the steps shown below.
3-(x - 1) = 2(x + 3)
Step 1: 3 -x-1 = 2(x + 3)
Step 2: 3-x-1 = 2x + 6
Step 3: 2 - x = 2x + 6
Step 4: 2 = 3x + 6
Step 5: -4 = 3x
Step 6:=x
Part A: Identify the step that Teddy made his error in and describe
the error.
