Solve Equation of One Variable
To solve a linear equation isolate the variable, that is bring the variable to one side with arithmetic operations.
Example:
To solve ax+b=c use the following steps:
1.ax+b=c, subtract b from both sides
2.ax=c-b, divide both sides by a
3.x=(c-b)/a
Remember:
All linear equations of one variable can be written as ax+b=c and the solution is x=(c-b)/a.
