Answer:
(0, 3 )
Step-by-step explanation:
Given the 2 equations
x + 3y = 9 → (1)
- 2x + 2y = 6 → (2)
Multiplying (1) by 2 and adding to (2) will eliminate the x- term
2x + 6y = 18 → (3)
Add (2) and (3) term by term to eliminate x, that is
0 + 8y = 24
8y = 24 ( divide both sides by 8 )
y = 3
Substitute y = 3 into either of the 2 equations and solve for x
Substituting into (1)
x + 3(3) = 9
x + 9 = 9 ( subtract 9 from both sides )
x = 0
solution is (0, 3 )
X= 0 y= 3
You have to make either the xs or ys the same so you could find out the other value first

Answer:
<h2>x = 5</h2>
Step-by-step explanation:
4x-2(3)=2y
4x-6=24
12-2(-6)=24
y=-6
12+12=24
The answer would be A= 3 because, 3x3= 9 then you add 9+1 and get 10
Hope this helps
