Question

solve for a
4a - 12 = 6a - 30
a =?

Explanation:

Step1: Move like - terms to one side

Subtract \(4a\) from both sides:
\(4a - 12-4a=6a - 30-4a\)
\(- 12 = 2a-30\)

Step2: Isolate the term with \(a\)

Add 30 to both sides:
\(-12 + 30=2a-30 + 30\)
\(18 = 2a\)

Step3: Solve for \(a\)

Divide both sides by 2:
\(\frac{18}{2}=\frac{2a}{2}\)
\(a = 9\)

Answer:

\(9\)
