<h3>Amar sold 5 Kodak Black shirts and 9 Blueface shirts</h3>
<em><u>Solution:</u></em>
Let "x" be the number of Kodak Black shirts sold
Let "y" be the number of Blueface shirts sold
Cost of each Kodak Balck T-shirt = $ 20
Cost of each Blueface T-shirt = $ 15
<em><u>Amar made 235 dollars and sold 14 T-shirts</u></em>
Therefore,
x + y = 14 ------- eqn 1
<em><u>Given he made 235 dollars</u></em>
Therefore,
<em><u>Solve eqn 1 and eqn 2</u></em>
<em><u>Multiply eqn 1 by -20</u></em>
-20x - 20y = -280 ------ eqn 3
<em><u>Add eqn 2 and eqn 3</u></em>
20x + 15y = 235
-20x - 20y = -280
( + ) ----------------------
-5y = -45
y = 9
<em><u>Substitute y = 9 in eqn 1</u></em>
x + 9 = 14
x = 14 - 9
x = 5
Thus he sold 5 Kodak Black shirts and 9 Blueface shirts
