Question

use elimination to find x and y

(a) ((x+2)/3) + ((y-2)/3) = -13
(b) x-y = - 8

Answer 1

those fractions look like a drag
multiply by 3 and start with \[x+2+y-2=-39\]

Answer 2

or just \[x+y=-39\\
x-y=-8\]

Answer 3

the y's cancel out and you're left with x=-47
Plug that back into one of the equations (I chose x-y= -8) and you should get y=-39)

(-47, -39)

Answer 4

@svan correct process but watch your basics
when you add then 2x = -47
