One number is four more than a second number. two times the first number is 10 more than four times the second number

Write an equation for each statement:

:

"one number is four more than a second number."

x = y + 4

:

" two times the first number is four more than four times the second number"

2x = 4y + 4

;

From the 1st equation, substitute (y+4) for x in the above equation

2(y + 4) = 4y + 4

2y + 8 = 4y + 4

8 - 4 = 4y - 2y

4 = 2y

y = 4%2F2

y = 2, the second number

and

x = 2 + 4

x = 6, a number

step-by-step explanation:

you get texts and minutes, so why not

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.
