Answer:
x=-5, y=2. (-5, 2).
Step-by-step explanation:
2x+y=-8
3x-5y=-25
------------------
5(2x+y)=5(-8)
3x-5y=-25
-------------------
10x+5y=-40
3x-5y=-25
--------------------
13x=-65
x=-65/13
x=-5
2(-5)+y=-8
-10+y=-8
y=-8-(-10)=-8+10=2
Answer: 18
Step-by-step explanation: 5m - 7 = 6m + 11
Solve for M
5m - 6m = 11+ 7
-m = 18
Divide both sides by -1
-m/-1 = 18/-1
m = -18
