put this solution on YOUR website!Let the 3 numbers be: x, y z
:
Write and equation for each statement:
:
"The sum of three numbers is one-hundred twenty-three."
x + y + z = 123
:
" the second number is two more than twice the first number:
y = 2x + 2
:
"the third is five less than the product of three and the first number."
z = 3x - 5
;
find the three numbers.
:
Substitute for y and z in the total equation
:
x + (2x+2) + (3x-5) = 123
:
6x - 3 = 123
:
6x = 123 + 3
:
6x = 126
x =

x = 21
:
Use the other two equations to find y and z, check the total

has this been set up enough for you??
