Linear Equations Complex Examples Linear Equation in one Variable Linear Equation in Two Variables Difference between Linear Equation in One & Two Variables Linear Expression

Let's study some complex examples related to linear equations and try to solve them

Example - 1 : A number added to its two-thirds is equal to 45. Find the number
Solution : Let the number be x
two-third of the number is 2/3 x

x + 2/3 x = 45

3x + 2x / 3 = 45
5x / 3 = 45
5x = 45 X 3
5x = 135
x = 135 / 5
x = 27
The number is 27




Example - 2 : The sum of two numbers, one of which is 2/3 times, the other is 50, Find the two number
Solution : let the number be x
two-third of the number is 2/3x

x + 2/3x = 50
3x + 2x / 3 = 50
5x / 3 = 50
5x = 50 X 3
5x = 150
x = 150 / 5
x = 30

so one number is 30
other number is 2/3 x 30 = 20
