Can someone help me with this problem?
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?
