Question

Solve the following system of equations
x - y = 16
2x + y = 2

Answer 1

y=x-16
2x+x-16=2
3x=18
x=6
y=-10

Answer 2

is that all you have to do

Answer 3

yepp. you solve the first equation in terms of either variable (I solved it in terms of x, aka i solved for y). Then I plugged that into the second equation, so all i had left in the second equation was a bunch of x's. Once I solve the value of x, I just plug that back into either original equation, and solve the value of y
