Answer:
2 peoples
Step-by-step explanation:
both of them will 5 sweets
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!
17X-7Y. You add or subtract the same variables, in this case you only have two x's and one y. So you add them, because you have a addition sign. 13x+4x and you leave the Y alone, because there is not another Y variable.
