Answer:
A: 42
Step-by-step explanation: 10.5x4=42
7x-23+11x+23=180
4x+0=180
4x/4=180/4
X=45
Answer: x=45
You can use substitution for this.
x+5 = 5x -11
Combine like terms
16=4x
Divide 4 on both sides to isolate the x
x=4
Plug x=4 to one of the equations
y= 4 +5
Combine like terms
y=9
So the answer is A. (4,9)
