Answer:
x=-2
y=3
Step-by-step explanation:
-3x+4y=18
multiply by 2
-6x+8y=36
and 6x+2y=-6
add
10 y=30
y=30/10=3
6x+2(3)=-6
6x=-6-6
6x=-12
x=-2
Answer: (-2,3)
Step-by-step explanation:
-3x + 4y = 18
6x + 2y= -6 we have to eliminate one of the variables so you will have ot
2(-3x + 4y) = 18(2) multiply the first equation by 2.
-6x + 8y = 36
6x + 2y = -6 now we could eliminate the x terms by adding them and
0 + 10y= 30 remember that is a new equation.
y= 3
Now we know that the y solution is 3 so we will put it into one of the equations and solve for x.
-6x + 8(3)=36
-6x + 24= 36
-24 -24
-6x = 12
x= -2
