What is the solution to this system of linear equations?

x - 3y = - 2

x + 3y = 16

(7, 3)

(3, 7)

(-2, - 3)

(-3, - 2)

Let's solve for x.

x-3y=-2

Step 1: Add 3y to both sides.

x-3y+3y=-2+3y

x=3y-2

Answer:

x=3y-2

Let's solve for x.

x+3y=16

Step 1: Add - 3y to both sides.

x+3y+-3y=16+-3y

x=-3y+16

Answer:

x=16+3y
