Question

How do you solve `10p = - 20`?

Answer 1

See explanation.

Explanation:

If one side of an equation contains a variable multiplied by a number and the other contains only a number to solve the equation you have to divide both sides by the number next to the variable. Here you divide both sides by `10`:

`10p=-20` - divide both sides by `10`

`p=-2` - this is the solution of the original equation.
