In the previous segment of Class 6 Maths, we learnt how to count terms. In this segment, we will learn about Solution of an equation.
What is the Solution of an equation?
An equation is said to be satisfied when its L.H.S. is equal to R.H.S after replacing the variable with a numerical value.
The value of a variable that can satisfy an equation is called the Solution of that equation. For example,
Consider the equation 6x + 3 = 21.
When x = 3 is put in the L.H.S, of this equation, then L.H.S. = 6(3) + 3 = 18 + 3 = 21 = R.H.S.
Thus, x = 3 satisfies the equation 6x + 3 = 21.
Hence, x = 3 is the solution of the equation 6x + 3 = 21.
What is a Linear equation in one variable?
An equation that consists of only one variable and whose highest power in the equation is 1 is called a Linear equation in one variable. They are also called as First degree equations in one variable.
● 6x + 45 = 81
● 17y = 10
● z – 6 = 4
