7- 7(-8 + x) = -14 + 4x how do you solve for x

First thing you need to do is distributive property and that will give you
 7-56-7x=-14+4x then combine like terms which will then give you
-49-7x=-14+4x Next get your letters on the left do that by subtracting 4x which will give you -49-11x=-14. After that you will add 49 to both sides which will give you
-11x= 35. Divide by -11 to get x=3.18  

Use distributive property first. Then combine like terms. Subtract the 4x from both sides. Then divide whatever you got and you get whatever x is. Hope it makes sense
