Question 1033401
let c represent the number of toys that campbell has.
let n represent the number of toys that noah has.


c = .5 * n + 2
this means that campbell has 2 more toys than half the toys that noah has.


c = .75 * n - 3
this means that campbell has 3 less toys than three quarters of the toys that noah has.


you have two equations that need to be solved simultaneously.


they are:


c = .5 * n + 2
c = .75 * n - 3


subtract the first equation from the second equation to get 0 = .25 * n - 5


add 5 to both sides of the equation to get 5 = .25 * n


divide both sides of the equation by .25 to get 5/.25 = n


solve for n to get n = 20


noah has 20 toys.


campbell has 2 more than half of noah's toys means that campbell has 12.


campbell has 3 less than three quarters of noah's toys means that campbell has 12.


the numbers check out.


noah has 20.
campbell has 12.
