Question

Eliminate the y in the following system of equations. What is the result when you add the two equations?

3x - 2y = 8
x + y = 6

Answer 1

.

Explanation:

Answer 2

X=4

Explanation:

3x-2y=8

x+y=6

multiply second equation by 2 so you can eliminate y

2(x+y)=2(6)

2x+2y=12

now add two equations together

first equation: 3x-2y=8

modified second equation 2x+2y=12

added together eliminates y. 5x+0=20

X=4
