x=-2
3y=4 x (-2)
y= 2
16.22 divided by 2 = your answer. (8.11)
Answer:

Step-by-step explanation:
simplify
by putting the negative sign on the outside. 
find the LCM of the denominators. It is (x-1)(x-2). Multiply by the LCM:

Simplify:

solve: 
X = 7. Because both lines equal the same so it has to equal 75
11 x 7 = 77
77-2 = 75
X = 7
