WEEK 1
TOPIC: SIMPLE EQUATION
This expression 3 x p= 18 is an algebraic sentence. It means three times an unknown numbers is equal to eighteen.
Translate the following equations into words.
5x + 7 = 37 it means if 7 is added to five times a number, the result is 37
11 = 3x – 1. It means 11 is equal to 3 times a certain number minus one.
TRUE AND FALSE STATEMENT
EXAMPLES: State whether the following is true or false
- X + 8 = 15 ( when x is 7)
- 3x – 4 = 11 ( when x is 6)
Solution
X + 8 = 15
7 + 8 = 15. Therefore the statement is true.
Solution
3x – 4 = 11
3*6 – 4 = 11
18 – 4 = 14 therefore the statement is false.
LINEAR EQUAUTION WITH MIXED OPERATION AND COLLECTION OF LIKE TERMS
When the operation are more than one,
- Eliminate the unwanted terms by either adding or subtraction
- Then eliminate the co efficient of the unknown by either multiplying or dividing.
Examples
- 4y – 5 = 7
Solution
Add 5 to both sides
4y -5 + 5 = 7 + 5
4y = 12
Divide both sides by the coefficient of the unknown
4y/4 = 12/4
Y = 3
- 5x -10 = 15x -60
Solution
5x – 10 = 15x – 60
Collect the like terms
5x -15 x = -60 + 10
-10x = -50
Divide both sides by -10 (Coefficient of the unknown)
-10x/-10 = -50/ -10
X = 5.
Do these
Solve the following equation
- 6m + 2 = 20 + 5m
- 4c – 8 = 10 – 5c
- 5x +5 = 35+ 2x
- 56 +7y = 5y + 16
