Question

I just had my math final and I got stuck with this problem. What is the answer?
3 = -1 (x+11) + 1
4 4x 2x

Lower numbers are the denominators

Answer 1

you were supposed to find x?

Answer 2

yes

Answer 3

Common denominator

Answer 4

8 or 4?

Answer 5

(-1(x+11)+2 ) /4x
(-x-11+2)/4x
3/4=(-x-9)/4x
Time both side by 4x
12x/4=-x-9
3x=-x-9
4x=-9
x=-9/2
if I didn't screw anything up

Answer 6

Answer 7

multiply it all by 4x to clear the fractions

Answer 8

3 = -1 (x+11) + 1
---------------- * 4x
4 4x 2x


3x = -1 (x+11) + 2

Answer 9

3x = -x -11+2

4x = -9

x = -9/4
