The step by step solution of the equation is 9 (2x+1/3)=39 ⇒ 18x + 3 = 39 ⇒ 18x = 36 ⇒ x = 2.
There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.
A formula known as an equation uses the same sign to denote the equality of two expressions.
In another word, the equation must be constrained with some constraints.
Given,
9 (2x+1/3)=39
By multiplication
⇒ 18x + 3 = 39
Taking 3 into the right-hand side
⇒ 18x = 36
Divide 18 on both side
⇒ x = 2.
Hence the answer to the equation will be 2.
