Cost of 1 shirt is
and cost of one sweater is
<u>Solution:
</u>
Given that Jane’s buying clothes.
She can get 5 shirts & 4 sweaters for 
She can get 2 shirts & 3 sweaters for 
Need to determine cost of 1 shirt and 1 sweater.
Let assume cost of 1 shirt = 
And assume cost of 1 sweater = 
Let us create equations from give conditions
First condition is Cost of 5 shirt + cost of 4 sweater = 

So using first condition equation which we get is as follows

Second condition is Cost of 5 shirt + cost of 4 sweater =

So using second condition equation which we get is as follows

Now we have two equations to be solved

On multiplying equation (1) by 2 and equation (2) by 5 to make coefficients of x equal in both equations, we get

On subtracting (3) from (4), we get

On substituting y = 26 in equation (1) we get

Cost of 1 shirt =
Cost of 1 sweater =
