Question

What is the value of a for the equation -8a+32=72

Answer 1

`a=-5`

Step-by-step explanation

`-8a+32=72`

to find a , we need to isolate it

Step 1

subtract 32 in both sides

`\begin{gathered} -8a+32=72 \\ -8a+32-32=72-32 \\ -8a=40 \end{gathered}`

Step 2

divide both sides by -8

`\begin{gathered} -8a=40 \\ (-8a)/(-8)=(40)/(-8) \\ a=-5 \end{gathered}`

I hope this helps you
