An equation and the steps to solve it are shown below: 3x - one over two (8x - 2) = 4 step 1: 3x - 4x + 1 = 4 step 2: x + 1 = 4 step 3: x + 1 - 1 = 4 - 1 step 4: x = 3 which step was the error made and why?

The equation is expressed as 3x- 0.5 * (8x-2). In this case, the first step is through distributive property resulting to 3x - 4x + 1 = 4. The incorrect step is the proceeding step (step 2) in which x should have negative sign instead of positive as -4x + 3x is -x. This affects the proceeding steps and thus the answer.

It’s 24.6 after you round to the nearest tenths the answer should be 25.0
