Answer:
x=-3
y=4
Step-by-step explanation:
2x+3y=6
2x+y=-2
solve for y
y=-2-2x
substitute
2x+3(-2-2x)=6
simplify
2x-6-6x=6
2x-6-6x+6=6+6
-4x=12
x=-3
substitute x
2(-3)+y=-2
-6+y=-2
y=4
Answer:
The solution is x = -3, y = 4.
Step-by-step explanation:
2x + 3y = 6
2x + y = -2
This one ius quite straight forward to solve using elimination.
As 2x is common to both equations we can eliminate 2x by subtraction:
0 + 3y- y = 6 - (-2)
2y = 8
y = 4.
Next, we plug y = 4 into the first equation:
2x + 3(4) = 6
2x = 6 - 12
2x = -6
x = -3.
