Question

2x − one over four (12x + 4) = 3

Step 1: 2x + 3x + 1 = 3
Step 2: 5x + 1 = 3
Step 3: 5x + 1 − 1 = 3 − 1
Step 4: 5x = 2

In which step was the error made and why?

Answer 1

2x - 1/4(12x + 4) = 3
2x - 3x - 1 = 3 ---- he did not distribute the -1/4 properly....he forgot the negative sign when distributing.
