Question

Solve for this equation:3/4p-2=7

Answer 1

3/4p - 2 = 7

Add 2 to both sides.

3/4p = 9

Divide both sides by 3/4 to isolate the variable p.

p =
`\boxed {12 }`

Answer 2

Here is the equation:

`(3)/(4)p - 2 = 7`

Switch the equation around and it becomes:

`7 + 2 = (3)/(4) p \\ 7 + 2 = 9 \\ \\ (3)/(4)p = 9`

The sign changes. At first you were subtracting, and now you're adding. Divide both sides by
`(3)/(4)` to leave the variable alone.

`(3)/(4) p / (3)/(4) = p \\ \\ 9 / (3)/(4) = 12`

That means p = 12
