Answer:
(1,2)
Step-by-step explanation:
We arbitrarily set out to eliminate x and then find y.
Keep 4x-3y=18 as is, but multiply 2x+y=4 by -2. We get -4x - 2y = -8.
Combine:
4x - 3y = 18
-4x - 2y = -8
-------------------
-5y = -10
Solving for y, we get y = 2.
To find x, substitute y = 2 into either of the given equations. If we choose the second equation, we get 2x + (2) = 4, so that 2x = 2 and x = 1.
The solution is (1, 2).
