What are Linear Equations in one variable ??
Simple Equations in one variable is a condition wherein , algebraic expressions are expressed with an equal sign with only one variable (x or y or z) in Linear equation.
Lets see an example for some simple equations
3x + 5 = 11
In the above equation note the following
- 3x is algebraic expression
- X is variable (only 1 variable)
- The power of variable is 1.
- Change in variable value changes result of equation.( Equation holds true or not)
Lets solve a few equations
Q.1 5(x+1) = 6
Ans : 5*x + 5*1 = 6
5x + 5 = 6
Substracting 5 on both sides
5x + 5 – 5 = 6 -5
5x = 1
