Solve for a,a.

Question

minus, 90, equals, minus, 6, a, minus, 12
−90=
−6a−12

Answer 1

To solve the equation \(-90 = -6a - 12\), we can follow these steps:

1. Add 12 to both sides to isolate the term with \(a\):

   \[ -90 + 12 = -6a \]

   This simplifies to:

   \[ -78 = -6a \]

2. Divide both sides by -6 to solve for \(a\):

   \[ a = \frac{-78}{-6} \]

   Simplifying the right side gives:

   \[ a = 13 \]

Therefore, the solution is:

\[ a = 13 \]
