S+m+l=28
4s+2m+l=58
6s+5m+4l=135

Eliminate the variable l from the first 2 equations

s+m+l=28
-4s-2m-l=-58
-3s-m=-30

Elminiate the variable l from the last 2 equations

6s+5m+4l=135
-16s-8m-4l=-232
-10s-3m=-97

Now solve for s and m using the 2 equations without l

-3s-m=-30
-10s-3m=-97

9s+3m=90
-10s-3m=-97
-s=-7
s=7

Then plug in s into one of the equations without l

-3(7)-m=-30
-21-m=-30
-m=-9
m=9

Now plus in s and m into one of the original 3 equations

(7)+(9)+l=28
16+l=28
l=12

Final answer:
Small=$7
Medium=$9
Large=$12

I know it only asks for large but I wanted to show you how to find them all for future reference. :)

Answer: x=

y+20

Step-by-step explanation

240=12x+8y

Step 1: Flip the equation.

12x+8y=240

Step 2: Add -8y to both sides.

12x+8y+−8y=240+−8y

12x=−8y+240

Step 3: Divide both sides by 12.

12x

=
