Question

The sum of three numbers is 164. The second number is 3 more than twice the first number, and the third number is four times the first number. What are the three numbers

Answer 1

23, 49, and 92

Explanation:

three numbers x, y, z

x+y+z=164

y=2x+3

z=4x

we have three equations and two of them are in terms of x so we can solve for x first by plugging in the two equations to our first equation

x+2x+3+4x=164

7x+3=164

7x=161

x=23

then find y

y=2(23)+3=46+3=49

then find z

z=4(23)=92
