Solve the following equation for "y": 3x-4y=20

y = -5

Step-by-step explanation:

to find any y intercept, make x equal zero.

Step-by-step explanation:

20=3x-4y, add 4y to each side

4y+20=3x, subtract 20 from each side

4y=3x-20, divide each side by 4

y=(3x-20)/4 or if you prefer

y=0.75x-5

$20.01

step-by-step explanation:

the sale price is (1.00 - 0.77)($87), or 0.23($87), or $20.01.

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
