Question

One number is six times another number. Their difference is 35. What are the two numbers?

a.) 5 and 30
b.) 8 and 48
c.) 7 and 42
d.) 6 and 41

Answer 1

letter c

Explanation:

Answer 2

x - y = 35
x = 6y
Plug 6y in for x in the first equation.
6y - y = 35
5y = 35
Divide both sides by 5
y = 7
x = 6y
x = 6(7) = 42
42 and 7
Letter C
Since we had the answers we could have just tried the answers but you will not always have multiple choice so this is the method for solving.
