Answer:
Step-by-step explanation:
3x+8y=-5
-2x+2y=18
Ok, so you want to get either x or y to cancel out so lets multiply the first equation by 2 and the second equation by 3.
6x+16y=-10
-6x+6y=54
Now x can cancel out. The new equation is:
22y=44
y=2
Now you input 2 into one of the original problems.
-2x+2(2)=18
-2x+4=18
Now subtract 4 from both sides.
-2x=14
Divide
x=-7
Now check your answer.
-2(-7)+2(2)=18
14+4=18
