2x– 5(x– 3) = 2 (x– 10)

2x-5(x-3)=2(x-10)

First multiply the parentheses.

2x-5x+15=2x-20

Then combine like terms.

-3x+15=2x-20

Then add 20 to both sides.

-3x+35=2x

Then add 3x to both sides.

35=5x

Finally, divide 5 from both sides.

7=x

hope it helps!

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
