Question

solve for a.
36a - 30a + 30a = -36
a =

Explanation:

Step1: Combine like terms

First, we look at the left side of the equation \(36a - 30a + 30a\). The terms \(-30a\) and \(+30a\) cancel each other out (because \(-30a + 30a = 0\)). So we are left with \(36a\) on the left side. So the equation simplifies to \(36a=-36\).

Step2: Solve for \(a\)

To solve for \(a\), we divide both sides of the equation \(36a = - 36\) by 36. Using the division property of equality, we have \(a=\frac{-36}{36}\).
Simplifying \(\frac{-36}{36}\), we get \(a = - 1\).

Answer:

\(-1\)
