Grade 5 - Mathematics
1.5 Equations

  • Numeric expression: Is an expression with numbers.
    Example: 45 + 34
  • Numeric equation: Is a numeric expression equated to zero.
    Example: 45 - 45 = 0
  • Algebraic expression: Is an expression that contains both numeric and unknown variables.
    Example: x - 5
  • Algebraic equation: Is an algebraic expression equated to zero. Here you can solve for the variable.
    Example: x - 5 = 0
    x - 5 + 5 = 0 + 5
    Therefore x = 5
The following are the points to remember while solving an algebraic equation :
  1. We can add/subtract the same number to/from both sides of an equation.
  2. We can multiply/divide the same number to/by both sides of an equation.
  3. We can transfer the terms from one side to the other side after changing their signs.
Example: 2x - 5 = 31
Step 1: Adding 5 both sides 2x - 5 + 5 = 31 + 5
Therefore, 2x = 36
Step 2: Dividing both sides of the equation by 2 we get
x/2 = 36/2
Therefore, x = 18
