Solve using the substitution method

x + 3y = −8,

4x − 3y = 23

3y= -8-x
sub that into the second equation
to get
4x - (-8-x) = 23
open brackets to get 5x = 15
x = 3
then 3 + 3y = -8
3y = -11
y = -11/3

Your work is correct. my teach said this

Question

Solve using the substitution method

3y= -8-x
sub that into the second equation

open brackets to get 5x = 15
x = 3
then 3 + 3y = -8
3y = -11
y = -11/3

Your work is correct. my teach said this <<<

I probably would have solved the first equation for x because its coefficient is 1.

You must state your answer as an ordered pair. and she told me this <<<< can some help
