Question

How do I solve this system of equations using the elimination method.(I don't just want the answer, I want an explanation on how to get the answer.)

y=3x+13
2x=y-9

Answer 1

Explanation:

Substitute 1 in 2 and solve for x.

2x=y-9

2x=3x+13-9

2x = 3x+4

-x = 4

x = -4

Then use equation 1 to solve for x.

y = 3x+13

y = -12+13

y= 1

Answer 2

y=3x+13

2x=y-9
