Xy - 5 = k (move the known term to the right with changed sign)

xy = k + 5

Now we have x multiplied for y...to delete the y, divide both terms for y.

xy/y = (k+5)/y

x = (k+5)/y

3y + 5x = 7

Move 3y to the right with changed sign (this to make x the variable for which we solve the equation)

5x = 7 - 3y

Divide every term for 5

5x/5 = 7/5 - 3y/5

x = 7/5 - 3y/5

m/n = p-6

Multiply both terms for n, since we should delete the fraction m/n

m = pn-6n

Factor...

m = n(p-6)

to find n, move m to the right with changed sign.

Divide both for p-6

m/p-6 = n

n = m/p-6

F = 9c/5 + 32

9c/5 + 32 = F

Move 9c/5 to the left (don't change sign) to make it the default variable. And move all the rest to the right but changing sign.

9c/5 = f - 32

To delete the fraction, multiply every term for 5

9c = 5(f) + 32(5)

9c = 5f - 160

Divide both for 9

c = 5f/9 - 160/9

In-s [12.5K]

Answer:

Joe saved 68.25

Step-by-step explanation:

Subtract 6.85 from 80, you get 73.15

Subtract 5.50 from 73.15 and you get 67.65.

Subtract 21.40 from 67.65 and you get 46.25.

Add 22 to that amount, you get 68.25.
