Answer :

Certainly! Let's solve the equation [tex]\(5a - 2b = 15\)[/tex] for [tex]\(a\)[/tex] step-by-step.

### Step-by-Step Solution:

1. Start with the given equation:

[tex]\[ 5a - 2b = 15 \][/tex]

2. Isolate the term involving [tex]\(a\)[/tex]:

To isolate [tex]\(5a\)[/tex], add [tex]\(2b\)[/tex] to both sides of the equation:

[tex]\[ 5a - 2b + 2b = 15 + 2b \][/tex]

Simplifying this, we get:

[tex]\[ 5a = 15 + 2b \][/tex]

3. Solve for [tex]\(a\)[/tex]:

To solve for [tex]\(a\)[/tex], we need to divide both sides of the equation by 5:

[tex]\[ a = \frac{15 + 2b}{5} \][/tex]

4. Simplify the expression:

Split the fraction into two separate fractions to simplify:

[tex]\[ a = \frac{15}{5} + \frac{2b}{5} \][/tex]

5. Calculate the division:

Evaluate the fractions individually:

[tex]\[ \frac{15}{5} = 3 \quad \text{and} \quad \frac{2b}{5} = \frac{2}{5}b \][/tex]

6. Combine the results:

Finally, combine the terms to express [tex]\(a\)[/tex]:

[tex]\[ a = 3 + \frac{2}{5}b \][/tex]

So, the solution to the equation [tex]\(5a - 2b = 15\)[/tex] for [tex]\(a\)[/tex] is:

[tex]\[ a = \frac{2b}{5} + 3 \][/tex]

This is the simplified form of [tex]\(a\)[/tex] in terms of [tex]\(b\)[/tex].
