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.
[tex]a*c=b*c[/tex]
First, you multiply by 3 from both sides of an equation.
[tex]3*\frac{1}{3}a=3(-5)[/tex]
And, then you simplify or solve equation.
[tex]3(-5)=-15[/tex]
[tex]a=15[/tex]
[tex]15/3=5[/tex]
[tex]15/5=3[/tex]
[tex]3*5=15[/tex]
[tex]5*3=15[/tex]
Hope this helps!
Thanks!

Have a great day!
