In the definition of linear equation with one variable, "all formulas with unknowns are integral" is illustrated with specific examples

Linear equation with one variable: an integral equation with one unknown number and one unknown number is called linear equation with one unknown number
For example: 2x + 3 = 7, contains an unknown number x, the degree of X is 1, 2x + 3 on the left side of the equal sign and 7 on the right side of the equal sign are integers
So this kind of equation is one variable one degree equation
But 2 / x + 3 = 7, although it contains an unknown x, 2 / x + 3 on the left side of the equal sign is not an integral, so it is not a linear equation of one variable
