Answer:
[tex]B= \frac{S + 7}{A}[/tex]
Step-by-step explanation:
We are given the following equation:
S = BA - 7
And we want to solve it for B.
This is a literal equation, and to solve these, we need to isolate the variable we are solving for (in this case, B) on one side.
Here's the equation again:
S = BA - 7
We can start by adding 7 to both sides (removes it from the right side).
S = BA - 7
+7 +7
________________
S + 7 = BA
Now, divide both sides by A to isolate B. Remember that we're dividing both S AND 7 by A.
(S + 7) = BA
÷A ÷A
[tex]\frac{S+7}{A} = B[/tex]
This can be rewritten to be: [tex]B = \frac{S + 7}{A}[/tex]
You can also write it as [tex]B = \frac{S}{A} +\frac{7}{A }[/tex] if you wish.
