Question

17. Solve for p in the equation 7p = –63.

A. p = –9
B. p = 9
C. p = –70
D. p = –56

Answer 1

It’s A

Explanation / when you multiply 7 by -9 you get -63

Answer 2

`p=-9`

Explanation:

We want to solve the linear equation;

`7p=-63`

We divide both sides of the given linear equation by 7 to obtain;

`(7p)/(7)=(-63)/(7)`

This implies that;

`p=(-63)/(7)`

`p=(-9*7)/(7)`

We now cancel out the common factors to get:

`p=-9`
