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!

Answer:

Step-by-step explanation:

Ix-4I+3=3

Ix-4I+3-3=3-3

Ix-4I=0

x-4=0

x-4+4=0=4

x=4

checking:

I4-4I+3=3

I0I+3=3

3=3

Question:

Escape park owner want 30% of each order to include long boards he wants to know how many long boards to order out of a total of 50 skateboards

x = 30% of y

x = 0.3y .....1

But, the total number of skateboard is given as 50

y = 50
