Answer:
The answer to your question is (3, -6)
Step-by-step explanation:
Data
x - 2y = 15 Equation l
2x + 4y = -18 Equation ll
Solve the system of equations by elimination
-Multiply equation l by 2
2x - 4y = 30
2x + 4y = -18
4x + 0 = 12
4x = 12
x = 12/4
x = 3
-Substitute x in equation l
3 - 2y = 15
-Solve for y
-2y = 15 - 3
- 2y = 12
y = 12/-2
y = -6
-Solution
(3, -6)
