Question

The sum of two numbers is 86. One of the numbers is five less than three times the other. What are the two numbers?

Answer 1

x+y=86
x is five less than three times the other (x+5=3y)

Answer 2

easiest way to solve this would be ot move the 5 to other side and sub in

Answer 3

X+y=86
x-5=3y
x=5+3y

5+3y+y=86
4y=86-5
4y=81
Y=81/4
Y=20.25

X+y=86
X+20.25=86
X=86-20.25

Answer 4

so i seem to not understand why you make it x+5=3y? i was reading it asx-5=3y

Answer 5

so it says that one of the numbers is 5 less than 3 times the other number. So that means x= 3y-5. This shows that x is 5 less than whatever 3y is, you get the 3y first, then subtract 5.
