3s + 4p = 123
3s + 2p = 85.5
Subtract second equation from the first.
2p = 37.5
p = 18.75
You should be able to work it from here.
3 sweatshirts and 2 sweatpants for 85.50 --> 3x+2y=85.50
3 sweatshirts and 4 sweatpants for 123 --> 3x+4y=123
solve for one of the variables in either equation (in terms of the other variable) and insert the answer into the other equation to get an actual value of the other variable
x=28.5-(2/3)y --> insert the "x" value into the other equation to solve for "y"
y=18.75 --> now insert the "y" value into the first equation to get an actual value for "x"
FINAL ANSWER:(x=16 and y=18.75)
