For this case we have the following system of equations:

We can write a system of equivalent equations.
For this, it is enough to multiply one of the two equations by a scalar.
Multiplying the equation 1 by 2, we have:

Therefore, the new system of equations is:

Answer:
A system that is equivalent is:
D) 
Answer:its actually 124
Step-by-step explanation:
1) can't answer w/o a graph
2) just plug each one in the the equation (remember that a point is (x,y)) so you plug (-5) in for y and (-1) in for x
(-5)=(-1)–4
-5=-5 ✓
(-1,-5) is the answer
