Solve for x
We need to rearrange the given equation so that x is by itself on one side of the = sign. To start, we can factor x out of the two terms on the left so we have
Next, we just divide both sides of the equation by the expression in parentheses and we have the answer. We can find a numerical value for x if we know y, but since y isn't given, the best we can do is give an expression for x in terms of y.
