Solve for the Variable Involving Addition, Subtraction, Multiplication, and Division
Use inverse operations to solve the equation for a variable.
For example, consider the equation a – 4 = 2.
Here, 4 is subtracted from a on the left side.
So, to find the value of a, we use inverse operation of subtraction, that is, addition.
Adding 4 to both the sides, we get:
a – 4 + 4 = 2 + 4
a = 6
