Answer: a = -24

Explanation:

Given equation:


\sf{30=26-\cfrac{a}{6}}

Subtract 26 from both sides:


\sf{30-26=-\cfrac{a}{6}}


\sf{4=-\cfrac{a}{6}}

Multiply both sides by 6:


\sf{4*6=-a}


\sf{24=-a}

Divide both sides by -1:


\sf{-24=a}

Therefore, a = -24.

Answer:

a = -24

Explanation:

Hi, the other guy is wrong btw so let me explain!

First, let's put a on one side and the constants on another by subtracting both sides by 26

30 - 26 = 26 - a/6 - 26

This will result in -a/6 = 4

To get rid of the negative sign and denominator of a, multiply by -6

a = -24
