Can someone explain how to do this?

y + 1/3 = -5/6

Isolate y by adding -1/3 to both sides:

(y + 1/3) + (-1/3) = -5/6 + (-1/3)

Addition is associative, meaning we can regroup the sums on the left side:

y + (1/3 + (-1/3)) = -5/6 + (-1/3)

1/3 and -1/3 cancel, so we're left with

y = -5/6 + (-1/3)

Adding a negative number is the same as subtracting:

y = -5/6 - 1/3

To combine the fractions and simplify the right side, you first have to find a common denominator. 6 is a multiple of 3, since 6 = 2•3. So multiply the numerator and denominator of 1/3 by 2:

1/3 • 2/2 = 2/6

So we get

y = -5/6 - 2/6

and because the denominators are identical, we can combine the fractions to get

y = (-5 - 2)/6

Simplify the numerator to get y :

y = -7/6

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.

step-by-step explanation:

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
