x * 3 + (1 - x) * 11 = 7

if I get rid of the parenthesis I’m left with:

x * 3 + 1 - x * 11 = 7

then I’m not sure what to do. If I combine the “x”s they will cancel out, so I thought maybe I should start with the multiplication and try to work through

3x + 1 - 11x = 7

-8x = 6

x= -.75

But I know it is wrong because x is obviously .5

Can someone tell me where I went wrong?
