Question

1) The sum of three numbers is 22. The second is 3 more than the first. The third is

one less than twice the first. Find the numbers.

Answer 1

Answer: The numbers are 5, 8, and 9

Explanation:

x+y+z=22

y=x+3

z=2x-1

After you have those three equations, you can plug the y and z value into the first equation.

You get x+x+3+2x-1=22, so 4x+2=22

Therefore, 4x=20, so x=5

If x=8, then y=5+3, so y=8

Also, z=2(5)-1, so z=9
