Question

Solve the equation for the specified variable.
S = BA-7, for B

Answer 1

`B= (S + 7)/(A)`

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

`(S+7)/(A) = B`

This can be rewritten to be:
`B = (S + 7)/(A)`

You can also write it as
`B = (S)/(A) +(7)/(A )` if you wish.
