The characteristics of a linear equation in one variable : has only one variablemust have equal sign (=)the power of the variable is one
Generally it is written as ax + b = 0
Example of Linear Equations in One Variable
x + 5 = 8 3n + 1 = 6n 4k - 3 = 8 5y = 3
2x - 1 9x + 8y = 10a - 4b = 6m + 5 = 12
2x - 1 is not a linear equation in one variable because there is no equal sign. 9x + 8y = 10 is not a linear equation in one variable because it has two variables, x and y.
a - 4b = 6 is not a linear equation in one variable because it has two variables, a and b.m + 5 = 12 is a linear equation in one variable because it has one variable, equal sign and the power of the variable is one.
