Exercise 1 Page 12

To solve an equation, we should first gather all of the variable terms on one side of the equation and all of the constant terms on the other side using the Properties of Equality. In this case, the variable term is already on the left-hand side of the equation, so we will start by subtracting from both sides of the equation.
Now, we can continue to solve using the Properties of Equality.
The solution to the equation is We can check our solution by substituting it into the original equation.
Simplify left-hand side
Since the left-hand side is equal to the right-hand side, our solution is correct.
