The value of the variable is eight divided by fifteen i.e, 8/15
What is variable ?
A variable in mathematics is an alphabet or phrase that stands in for an unknowable amount, unknowable value, or unknowable number. Particularly in the case of algebraic expressions or algebra, the variables are utilised. As an illustration, the linear equation x+9=4 has the variables x and 9 as constants.
Given that,
1/6 + s = 21/30 --------> (1)
Given equation is 1/6 + s = 21/30
s= 21/30 - 1/6
By taking LCM between two fractions,
s= 21-5/30
s=16/30
s=8/15
16 divided by 30 = 8/15
Hence, the number that the solution to the equation is 8/15
