 Intro to Linear Equations Solutions to a Linear Equation & Solving Linear Equations Graphically Solving Equation on Graphing Calculators 1st: Arrange the equation so it looks like:
ax + b= cx + d where some of the values may be zero.

2nd: Check the equation to see if the solution is
"all numbers" (for a true statement), or,
"no solution" (for a false statement).
See Solutions to a Linear Equation & Solving Linear Equations Graphically for help.
3rd: In the next step you may not use fractions.
If you don't know the decimal representation for a certain fraction, this page will complete the division for you.
Enter "- 2" as "-2."

fraction = /

fraction =

4th: Input DECIMAL OR INTEGER values.
Enter "- 2" as "-2."
Enter the values for a, b, c and d from the 1st Step.
Be as accurate as possible.
x + = x +

5th: Press the button to solve the equation.
,
The solution is .

"NaN" here means "an infinite number of solutions" - all numbers.
"Infinity" here means NO Solution -- no number will make the equation true.
