MEAP Preparation - Grade 6 Mathematics
2.98 Algebra (Find the Unknown)

  • Sometimes to solve a problem we have to form a mathematical equation. A letter or a text string is used to denote an unknown quantity while forming an equation. The unknown quantity is called a variable.
  • The equation may be solved to find the value of the variable.
  • While solving an equation, the variables are kept on one side and the numbers are transferred to the other side of the equation.

    x - 5 = 10
    Adding 5 to both sides of the equation we get,
    x - 5 + 5 = 10 + 5
    x = 15

    Substituting the value of x in the equation
    x - 5 = 10
    15 - 5 = 10
    True, therefore the value of x is correct.

  • Note: If we perform some operation on one side of the equation, the same operation should be performed on the other side of the equation as well.

Directions: Find the value of the variable in each question. Also write at least 10 equations of your own and solve for x and verify your answer.
Q 1: 18 = X + 6
