Answer 1

For the following system, if you isolated x in the first equation to use the Substitution Method, what expression would you substitute into the second equation?

-x + 2y = -6
3x + y = 8

Answer 2

first make x the subject for the first one
so,
x=6y+3

so,
you sub into x: 3(6y+3)+y=8
= 18y+9+y-8=0
19y+1=0
y = ........
.then, substitute the answer into an equation and find x

Hope it helps.
