The sum of two numbers is 21. the larger number is 6 less than two times a number. what are the two numbers? i need two

x + y = 21

x = 2y - 6

We have a value for x, so we can plug it into the original equation to solve for y.

2y - 6 + y = 21

Combine like terms.

3y - 6 = 21

Add 6 tot both sides.

3y = 27

Divide both sides by 3.

y = 9

Now that we have a value for x, we can plug it into the 2nd equation to solve for x.

x = 2(9) - 6

x = 18 - 6

x = 12

step-by-step explanation:

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
