Question

What is the solution to this system of linear equations? x − 3y = −2 x + 3y = 16

Answer 1

Explanation:

x-3y=-2

x+3y=16

2x=14

x=7

7-3y=-2

-3y=-9

y=3

(7,3)

Answer 2

x = 7 and y = 3

Explanation:

x − 3y = −2 ... equation 1

x + 3y = 16 ...equation 2

equation 2 - equation 1:

6y = 18

y = 3

Now substitute this into equation 1:

x - 9 = -2

x = 7

Therefore, x = 7, and y = 3
