Us the substitution method:

x+1/9y=11

18x+2y=90

To use it, we must solve for 1 variable

it seems to be that they want us to solve for x in firsr equation

x+1/9y=11

minus 1/9y from both sides

x=11-1/9y

sub 11-1/9y for x in other equation

18 (11-1/9y) + 2y=90

distribute

198-2y+2y=90

198=90

false

therefor there is no solution

(if we were to graph them they would be paraalell, if we rewrote them, they look like this: 18x+2y=192 and 18x+2y=90, obviously, there is no solution)

answer is no solution
