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.
