Question

How do you simplify `-\frac { 9x - 9y } { 8x } + \frac { 4x - 11y } { 8x }`?

Answer 1

`=(-5x-2y)/(8x)`

Explanation:

The denominators are already the same so the fractions can be combined into one.

`-(9x-9y)/(8x) + (4x-11y)/(8x)`

`=(-(9x-9y) +4x-11y)/(8x)`

`=(-9x+9y+4x-11y)/(8x)`

`=(-5x-2y)/(8x)`
