Question

I need help on all of these!

Answer 1

Given:

The given equation is $3(a+3)=15$

We need to determine the solution of the given equation.

Solution of the equation:

Step 1: To determine the value of a, first, we shall divide both sides of the equation by 3.

Thus, we get;

$\frac{3(a+3)}{3}=\frac{15}{3}$

Simplifying, we get;

$a+3=5$

Thus, dividing both sides of the equation by 3, we get $a+3=5$

Step 2: Finallly, subtracting both sides of the equation by 3, we have;

$a+3-3=5-3$

Simplifying, we get;

$a=2$

Thus, subtacting 3 from both sides of the equation, we have, $a=2$

Hence, the solution of the equation is $a=2$
