The cost of one sweater when the system of equations are solved is $10.

What is the cost of one sweater?

The cost one sweater can be determined by solving for s in the system of equations:

6s + 2j = 91  equation 1

3s + 4j = 92 equation 2

Given the system of equations, multiply  equation 1 by 2

12s + 4j = 182  equation 3

Subtract  equation 2 from  equation 3

9s = 90

Divide both sides of the equation by 9

s = 10
