Question

One number is 8 times another number. The numbers are both positive and have a difference of 70. Find the numbers.

Answer 1

Answer:

8x - x = 70

Step-by-step explanation:

8x - x = 70

that is equal to 7x = 70

divide by 7 on both sides

x will equal 10

substitute x for 10 in the original equation

you should get 8(10) - 10 = 70

8(10)=80

80 - 10 = 70

Answer 2

8x - x = 70
7x = 70
x = 10    ← one of the numbers
