the sum of three numbers is 125. the first number is 5 more than the third. the second number is 4 times the third. what are the numbers?

Answer 1

The equation should be:

(x+5)+4x+x=125

solve for x first:

6x+5=125

6x=125-5

6x=120

x=20

so 20+5=25, 4(20)=80,

so the numbers are:

25, 80, 20.
