Question

Solve the following system of equations using the elimination method.

x – 5y = 13

4x + 15y = 17
Question 2 options:

A)

(8,–1)

B)

(–4,6)

C)

(3,–1)

D)

(2,–9)

Answer 1

So for eliminating, you only solve for one variable first.

I solved for y, so I multiplied by -4 to eliminate the x.

Then I got y= -1

I then substituted that to one of the equations to get x.
