One number is 5 times another. If 18 is subtracted from the greater, the remainder will be 3 times the
smaller. Find the numbers.
You must use equations to solve,
Assume the bigger number is x and the smaller is y
X = 5y
And
X-8 =3y
We can just substitute x for 5y because of the first Equation
5y -8 = 3y
5y-3y = 8
2y = 8
Y=4
X=20
If we plug this in the two original equations, the first one will be automatically true,
20–8=3*4
12=12
Solutions are 20 for the big number and 4 for the smaller.
Hope this helps if you have any more questions, please ask!!!
