Question

solve the equation or formula for the variable indicated.
$3a + y = 5 + 5a$, for $a$

Explanation:

Step1: Isolate terms with $a$

Subtract $3a$ from both sides:
$3a + y - 3a = 5 + 5a - 3a$
Simplify to get: $y = 5 + 2a$

Step2: Isolate the $2a$ term

Subtract 5 from both sides:
$y - 5 = 5 + 2a - 5$
Simplify to get: $y - 5 = 2a$

Step3: Solve for $a$

Divide both sides by 2:
$\frac{y - 5}{2} = \frac{2a}{2}$
Simplify to get: $a = \frac{y - 5}{2}$

Answer:

$a = \frac{y - 5}{2}$
