Question

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

Answer 1

Hi there! :)

Answer:

a=-15

*The answer must have a negative sign.*

Step-by-step 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.

$3*\frac{1}{3}a=3(-5)$

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!
