Example Question #2675 : Isee Middle Level (Grades 7 8) Mathematics Achievement
Solve for x in the following equation:
To solve for x, we want to get x to stand alone or be by itself. So in the equation
we want x to be alone. To do that, we must cancel out the -4 with it. To cancel -4, we must add 4. If we add 4 to the left side of the equal sign, we must add 4 to the right side. So,
Example Question #20 : Solve Real World And Mathematical Problems By Writing And Solving Equations: Ccss.Math.Content.6.Ee.B.7
Solve for :
In order to solve this equation we need to isolate the variable to one side. Do not forget to perform the same operation on both sides of the equation.
Divide each side of the equation by :
Solve.

Example Question #1 : Word Problems
Mark is three times as old as his son Brian. In ten years, Mark will be years old. In how many years will Mark be twice as old as Brian?
In ten years, Mark will be years old, so Mark is years old now, and Brian is one-third of this, or years old.
Let be the number of years in which Mark will be twice Brian's age. Then Brian will be , and Mark will be . Since Mark will be twice Brian's age, we can set up and solve the equation:
Mark will be twice Brian's age in years.
Example Question #2 : Solve Word Problems Leading To Equations: Ccss.Math.Content.7.Ee.B.4a
Gary is twice as old as his niece Candy. How old will Candy will be in five years when Gary is years old?
Not enough information is given to determine the answer.
Since Gary will be 37 in five years, he is years old now. He is twice as old as Cathy, so she is years old, and in five years, she will be years old.
