Step-by-step explanation: Solving an equation means finding the value of the variable that makes the equation true.
Let's look at an example.
Solve the following equation.
3x + 1 = 7
To solve the equation, we need to get x by itself on one side and we do that by subtracting 1 from both sides to get 3x = 6. Now just divide both sides of the equation by 2 and we find that x = +2.
Thus, the solution to the equation is x = +2.
So the value of the variable is +2.
