Answer:
x=-15/2 and y=7
Step-by-step explanation:
y=-4x-23
y=-2x-8
Two methods, substitution and elimination. Elimination is the easiest, so you can subtract the equations.
y=-4x-23
-(y=-2x-8)
----------------------
y=-4x-23
-y=2x+8
------------ so solve :)
0=-2x-15
becomes 2x=-15
so x=-15/2
------------------------ plug in x to solve for y
and you get y=7

Answer:
14y + 32
Step-by-step explanation:
- First apply the distributed property: 24y + 32 - 10y
- Combine like terms: 24y - 10y = 14y
- Re-write: 14y + 32
I hope this helps!
