Question

Slove the following system of equations:
x-y=13
2x+y=2
what method would you use?

Answer 1

add the two equation first to solve for x, then put the value of x in any of the equation

Answer 2

so it would be (5,-8)?

Answer 3

Here I would use the elimination method....you can add these 2 equations and eliminate the variable 'y'

x-y=13
+(2x+y=2)
-----------
3x = 15

and that solves for 'x'

and then use that to solve for 'y'...

Answer 4

and yes that would be correct (5 , -8) is what I get too

Answer 5

Yes Great job @LeahL1111
