Solving linear equation in one variable
First-degree equations are equations with variables that have exponents of one. These equations can be solved using properties of equality like addition, subtraction, multiplication, and division. For example, an equation like x - 4 = 3 can be solved by adding 4 to both sides, resulting in x = 7.

Solving linear equation in one variable
- 2. They are alsocalled first-degree equation in the form ax + by=c.. are equations in one or more than one variables, where the variable has exponents equal to one.
- 3. is an equationof first- degree in one variable, it can be solve using real numbers and equality of property.
- 5. Example: x - 4= 3 x – 4 + 4 = 3 + 4 x + 0 = 7 x = 7 add 4 both sides
- 6. B. Subtraction property ofequality x + 2 = 5 Example: x + 2 – 2 = 5 – 2 x + 0 = 7 x + 2 = 5 subtract 2 both sides
- 7. C. multiplication propertyof equality Example: x / 11 = 4 11 ◦ x / 11 = 4 ◦ 11 X = 44 multiply 11 both sides
- 8. D. Division propertyof equality Example: 4x = 20 4x / 4 = 20 / 4 x = 5 divide 4 both sides
