[tex]a=-5[/tex]

Explanation

[tex]-8a+32=72[/tex]

to find a , we need to isolate it

Step 1

subtract 32 in both sides

[tex]\begin{gathered} -8a+32=72 \\ -8a+32-32=72-32 \\ -8a=40 \end{gathered}[/tex]

Step 2

divide both sides by -8

[tex]\begin{gathered} -8a=40 \\ \frac{-8a}{-8}=\frac{40}{-8} \\ a=-5 \end{gathered}[/tex]

I hope this helps you
