The sum of two numbers is 18. Twice the first number (x) minus the second number (y) is 6. Find the two numbers

8 and 10

Step-by-step explanation:

Set the first number as x, the second as y

x+y=18

2x-y=6

This is an binary system of first order equations

3x=24

x=8

y=10

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
