Honestly i agree with Nd12217 z is the answer to 136 x 150
Nevermind the answer is wrong
Answer:
X = -3. non-extraneous
Step-by-step explanation:
The given equation is 
We cross multiply to get:
Expand and multiply.
We factor to obtain:
Checking for extraneous solutions
Substitute x=-3 
.....Non-extraneous
Checking for x=6
....Non-extraneous
Add the equations,just the way they appear there.
-- Add the top 'x' to the bottom 'x'. Write the sum under the 'x's.
-- Add the '+y' and the '-y'. Write the sum under the 'y's.
-- Add the '2' and the '4'. Write the sum under them, with n " = " sign
before it.
You should now have an equation with only 'x' in it and no 'y'.
You can easily solve that one and find out the value of 'x'.
Once you know the value of 'x', go back to either one of the original
equations, and plug the number-value of 'x' in place of 'x'.
You'll then have an equation with only 'y' in it and no 'x'.
You can easily solve that one and find out the value of 'y'.
