Question

2(x-1/2x+1)2-5(x-1/2x+1)=12 x not= -1/2​

Answer 1

Step-by-step explanation:

would help if you showed all of your calculations. Otherwise, I'm forced to guess the steps you took to get x = -8/5.

Here's my best guess at what you did.

Take: 1/2x + 3/5 = 1 + 3/4x

Rewrite first term as: 2/4x + 3/5 = 1 + 3/4x

Subtract 3/4x from both sides: -1/4x + 3/5 = 1

Subtract 3/5 from both sides: -1/4x = -2/5

Multiply from both sides by -4 to get: 1/x = -8/5

At this point, we know that 1/x = -8/5, however we want to find the value of x (not 1/x)

Take: 1/x = -8/5

Invert both sides to get: x/1 = -5/8

In other words, x = -5/8

Is that what happened in your solution?
