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!

Factorize

(3n + 8) (3n - 8) = 0
3n + 8 = 0 and 3n - 8 = 0

Solve both for n

3n + 8 = 0
3n = -8
n = -8/3


3n - 8 = 0
3n = 8
n = 8/3

Therefore n = -8/3 and n = 8/3
