Answer:
Option C
Step-by-step explanation:
Given is a systems of equations in two variables a and b.
3a+b=10
-4a-2b=2
Let us solve this and find solution.
We can do this by elimination method
I equation x 2 gives
[tex]6a+2b =20\\-4a-2b=2[/tex]
Add these two equations to get
2a = 22
Divide by 2
We get a=11
Substitute in I equation
3(11)+B=10
b =10-33 =-23
Hence solution set is
(11,-23)
Option C is the right anser.
