28=-4 (2x+7) what does x equal

Well first lets do the distributive property so the left side is already done 28, now the right side - 4 (2x+7) when you do that you get - 8x-28. So now we have 28=-8x-28. So now I would move the - 28 to the left side and when you move stuff to the other side you change the sign so the sign will be positive 28+28 which is 56. Now you have 56=-8x. Now divide both side by - 8 to have - 7=x

Your Answer: x = - 7
