Solve the system using elimination.
x- y = -5
3x + y = 1
a (-1, 4)
b (-3, 4)
c (-1, 2)
d (2, -2)

A (-1, 4)

Step-by-step explanation:

x- y = -5

3x + y = 1

Add the two equations together to eliminate y

x- y = -5

3x + y = 1

4x = -4

Divide by 4

4x/4 = -4/4

x = -1

Now substitute x=-1 into the first equation

-1 -y = -5

Add 1 to each side

-1+1 -y = -5+1

-y = -4

Multiply by -1

y = 4

the answer is 99.
