### MEAP Preparation - Grade 5 Mathematics1.23 Solving for X

 While solving an equation, the variables are kept on one side and the numbers are transferred to the other side of the equation. Example: a + 2a + 7 - 5 = 10 Solution: Adding like terms: a + 2a + 7 - 5 = 10 3a + 7 - 5 = 10 3a + 7 - 5 = 10 3a + 2 = 10 Adding -2 to both sides of the equation we get: 3a + 2 -2 = 10 -2 3a = 8 Dividing both sides of the equation by 3 we get: 3a/3 = 8/3 a = 8/3 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 examples of equations of your own and solve for the variable.
