What does this equal? 4 (2x+1) - 2x=-8

4 (2x+1) - 2x=-8

4x+4-2x=-8

6x+4=-8

subtract 4 on both sides

6x=-12

divide both sides by 6

x=-2

To solve equations, you want to isolate the X. So, the first step will be to distribute that 4 into the 2x + 1.

4 x 2 = 8

4 x 1 = 4 So we have 4 (2x+1) = 8x+4. When we plug this into the equation, that gets us 8x + 4 - 2x = - 8. Next, let's combine like terms now that we've distributed everything out. 8x - 2x = 6x. Now we have

6x + 4 = - 8. Next, we subtract 4 from both sides to isolate the X; 6x = - 8 - 4. - 8 - 4 = - 12. So now we have 6x = - 12. The final step to isolating the X is to divide both sides by 6; 6/6 = 1, and - 12/6 = - 2. Our final answer is X = - 2.
