Three people are comparing their ages. charlie and ann's ages add to 5 years more than bob's age. charlie and bob's ages add to 6 years more than twice ann's age. ann and bob's ages add to 7 years more than four times charlie's age. set up a system of equations and solve for each person's age.

Solution:

we are given that

Three people are comparing their ages.

Let charlie age be x , ann's ages be y and bob age be z , then we can write using the given info

charlie and ann's ages add to 5 years more than bob's age.

Now using the given info. that charlie and bob's ages add to 6 years more than twice ann's age.

Again using -ann and bob's ages add to 7 years more than four times charlie's age.

Now we will solve these three equations together using calculator we get

x=34, y=57 and z=86

Hence  charlie age is  34 , ann's ages is 57 and bob age is 86.

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29
