Question

What is 1/3a = -5 what is a

Answer 1

Hi there! :)

Answer:

a=-15

*The answer must have a negative sign.*

Explanation:

This lesson it's about the solving one step- equations: multiplication and division.

Definition of multiplication property of equality.

Multiplication property of equality is multiplying both sides of an equation by the same number does not change the equation.

`a*c=b*c`

First, you multiply by 3 from both sides of an equation.

`3*(1)/(3)a=3(-5)`

And, then you simplify or solve equation.

`3(-5)=-15`

`a=15`

`15/3=5`

`15/5=3`

`3*5=15`

`5*3=15`

Hope this helps!

Thanks!
