Answer:
Step-by-step explanation:
Reducing 3 from numerator and denominator,
9x-22=23+4x
Now you subtract 4x from both sides to get the variable on one side..
5x-22=23
Now solve as you would solve a 2 step equation.
5x=45
Divide both sides by 5 to get the variable by itself.
x=9
B y=14 because if you subtract that will give you the answer
