Answer:
x=-2, y=4. (-2, 4).
Step-by-step explanation:
2x+y=0
5x+3y=2
----------------
-3(2x+y)=-3(0)
5x+3y=2
-------------------
-6x-3y=0
5x+3y=2
---------------
-x=2
x=-2
2(-2)+y=0
-4+y=0
y=0-(-4)
y=0+4
y=4
Answer:
x = -2, y = 4
Step-by-step explanation:
2x + y = 0
5x + 3y = 2
Multiply the top equation by -3 so that one variable can be eliminated:
-3(2x + y = 0)
5x + 3y = 2
Simplify the top equation:
-6x - 3y = 0
5x + 3y = 2
Add the equations:
-x = 2
Solve for x:
x = -2
Substitute x back into one of the equations:
5(-2) + 3y = 2
Solve for y:
-10 + 3y = 2
3y = 12
y = 4
