Michael wrote the system of equations below, but he accidentally left out the coefficient of x in the first equation.

y = ? x – 2

3y = 15x – 6

if the system has infinitely many solutions, what must the missing value be?

a. 2

b. 3

c. 5

d. 9

The answer is C, 5. This is because equation #2 is 3 times greater than the first equation, found by identifying 3y in the second equation. So 5*3=15.

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.
