Answer:
[tex]A=\frac{Y+8}{B}[/tex]
Step-by-step explanation:
So we have:
[tex]Y=AB-8\\[/tex]
First, add 8 to both sides. The right will cancel:
[tex]Y+8=AB[/tex]
Now, notice that A is multiplied to B. So, the isolate A, divide both sides by B. The right will cancel:
[tex]A=\frac{Y+8}{B}[/tex]
And we're done!
