Answer:
x=-2 and y=-3
Step-by-step explanation:
2x+4y=-16
-2(-2x+2y=-2)
2x+4y=-16
4x-4y=4
6x=-12
x=-2
2x+4y=-16
2(-2)+4y=-16
-4+4y=-16
+4 +4
4y=-12
y=-3
Answer: Combine like terms!

2.2222222(answer)
Answer:
−11
Step-by-step explanation:
Subtract
2-2-2
from both sides of the equation 10+2=−11\frac{y}{10}+2=-11 10y+2=−1110+2−2=−11−2
Simplify:
Subtract the numbers 10=−13
Multiply all terms by the same value to eliminate fraction denominators:
10=−13\frac{y}{10}=-1310y=−1310⋅10=10(−13
Cancel multiplied terms that are in the denominator
Multiply the numbers:
=−130
Solution:
=−130
