Step-by-step explanation:
X is equal to three in this
Answer:
X=4, y=-7
Step-by-step explanation:
To use elimination method, you want to cancel x or y when adding the equations together. So let’s multiply the first equation by -2
2(y)=2(-x-3)
2y=-2x-6
——————
add above equation 2y=-2x-6
to second equation Y=2x-15
add together. 3y=-21
Y=-7
—————————————-
solve for x by substituting y value (7) into either equation
y=-x-3
-7=-x-3
-4=-x
4=x
