The Grinch needs new clothes. He spends $131 on new clothes. The shirts he bought were $28 each and the pants he bought cost $15 each. If he bought a total of 7 pieces of clothes, then how many shirts (x) and pants (y) did he buy?

x = 5 and y = 2

Step-by-step explanation:

x = shirts

Shirts are 15 dollars

y = pants

Pants are 28 dollars

Some pairs that go up to 7 are

7-0

6-1

5-2

4-3

3-4

2-5

1-6

7-1

and if you do some elimination on ones that dont work you get 5 shirts and 2 pants.

5x15 is 75 and 2x28 is 56

75 + 56 = 131 and 131 = 131 so there are

5x and 2y

1. 3

2. 4

3. 1

hope this ! have a great day.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
