yes. sorry I was @ gym

Answer 4

help also @RomMosher go away

Answer 5

do you know how to use the substitution method?

Answer 6

or not at all

Answer 7

the elimination method is kind of like subtracting or adding whole equations
for example in this one
-8x+5y = 2
- -12x + 5x = -2

4x = 4
x=1

Answer 8

now that we have x, we can substitute x into the equation, both works
i'll just do both to show you

Answer 9

-8x+5y = 2
-8(1) + 5y =2
5x =10
x=2

Answer 10

-12x + 5y = -2
-12(1) + 5y -2
5y =10
y=2
