Solution

a
We can use the inverse operations in order to solve for The variable can be treated like a number so we'll subtract a from both sides.

b

To isolate  we have to add on both sides of the equation.

c

In this equation we have on the left-hand side. Thus, we can divide both sides by in order to solve for

d

To solve for we can multiply both sides by
