Answer:
x = 2, y = -1
Step-by-step explanation:
4x + 2y = 6 ------- eq 1
x − y = 3 -------- eq 2
Using elimation method:
eq 2 x 2
2 (x − y)= 2(3 )
2x - 2y = 6 ---- eq 3
eq 1 + eq 3
4x + 2y + 2x - 2y = 6 + 6
6x = 12
x = 2 (sub this back into eq 2)
x − y = 3
2 − y = 3
-y = 3 - 2
-y = 1
y = -1
Answer:
x = 2, y = -1
