Question

use substitution to solve the system -5x+24=27 and y=2x+11

Answer 1

What you do is replace y with 2x+11

Are you missing a y in your first equation? Is it 24x

If so,

-5x + 24(2x+11) = 27

solve for x and then solve for y.

Answer 2

X=10.5
y=13 ...so,

you place them in cordinate pairs, like this: (10.5,13)
x y
Hope this helped.
