The sum of 3 numbers is 9. tge second number is 3 less than the first. the thirf number is four morethan twice the first. find each number

x + y + z = 9

y = x - 3

z = 2x + 4

Because we have values for y and z, we can find the exact value of x, which we can use to find the exact values for the other variables.

x + x - 3 + 2x + 4 = 9

Combine like terms.

4x + 1 = 9

Subtract 1 from both sides.

4x = 8

Divide both sides by 4.

x = 2

Now that we have a value for x, we can plug this value in to each other x value to solve for y and z.

y = 2 - 3

y = -1

z = 2(2) + 4

z = 8

2
