D
Step-by-step explanation:
Answer:
A. Multiply 3x−3y=1 by 2, and multiply −2x+4y=2 by 3.
Step-by-step explanation:
Given


Required
A good first step
A good first step is to eliminate x and this is done as follows:
Multiply
by 2 (gotten from coefficient of x in the second equation)
Multiply
by 3 (gotten from coefficient of x in the first equation)
This gives:


Add both equations



<em>Hence (a), is true</em>
I'm pretty sure you add all the sides up together. So I think the answer to this would be 61 but I'm not 100% sure
