One number is five more than three times another. If their difference is 35, what is the larger number?
miv72 [106K]
Let x and y be the two unknown numbers. If one number, say x,is 5 more than 3 times another, say y, the equation would be

x = 5 + 3y

When their difference is 35, x-y = 35, since x is the much larger number here. We substitute x to solve for the smaller number, y.

x - y = 35
(5 + 3y) -y = 35
5 +2y = 35
2y = 35-5
2y = 30
y = 15

The larger number x would be
x = 5 + 3(15)
x = 50

The answer is 50.

X + y = 5 ; x - y =3 solve using linear combination
Bas_tet [7]

Answer:

x = 4

y = 1

Step-by-step explanation:

use one equation to solve for one variable.

y = 5 - x

Now plug the value of y in the other equation

x - (5-x) = 3

x+x= 3+5

2x=8

x=4

Now use the value of x to find the value of y on the first equation

y = 5 - x

y = 5 - 4

y = 1
