Answer:
reverse
Step-by-step explanation:
When you multiply or divide on one side of an inequaltiy, you have to mirror it on the other side and you have to reverse the inequality sign.
Let's multiply the first equation by -2 so that we can eliminate y.
-2x-4y=-20
3x+4y=8
X=-12
Since X is -12, let's plug it in to the equation to check.
-12+2y=10
2y=22; let's divide
y=11
So, D (-12,11)
