We can set up a system of equations to find the vaulues of the two unknown numbers.
The sum of two numbers is 93:
x + y = 93
The second is three more than four times the first;
y = 4x + 3
We can substitute y in the first equation in order to find the exact value of x.
x + (4x + 3) = 93
5x + 3 = 93
5x = 90
x = 18
Now we can plug this into the equation to find the exact value of y.
(18) + y = 93
y = 75
