how to solve a simple equation. You can solve a simple quadratic equation using the same rules that you used when solving linear equations. Solve the equation obtained in Step 2 to get the value of its variable.
The solver will then show you the steps to help you learn how to solve it on your own. The solution to the equation is therefore x 4. We can turn the two simple equations above into algebraic equations by substituting x for one of the numbers.
Lets solve the equation 3x 4 10 To remove the 4 we complete the inverse opposite operation by subtracting the 4.
Perimeter is equal to 2 times the length plus 2 times the width. Solve each zeroed equation independently. Solve the equation obtained in Step 2 to get the value of its variable. Simplify all brackets fractions etc if required.
