Let, Price of a shirt = x
Price of a Jeans = y
Equations would be: 4x + 3y = 150
x + 2y = 70
x = 70-2y
Substitute it into first equation,
4(70-2y) + 3y = 150
280 - 8y + 3y = 150
-5y = -130
y = 130/5
y = 26
Substitute it into 2nd equation,
x + 2(26) = 70
x = 70-52
x = 18
So, Cost of a Shirt = $18 & Cost of a Jeans = $26
Hope this helps!
