How do I input a linear equation using the built-in template ax + b = cx + d?
Select the "ax + b = cx + d" format in the Settings window.
 

Note: This window is available in the landscape orientation only.
Enter the values for a, b, c and d and click "Solve".
 
a, b, c and d could be whole numbers, fractions or decimals.
This format supports two modes: "Fractions" (coefficients could be whole numbers and fractions) and "Decimals" (coefficients could be whole numbers or decimals). Pressing "Fractions" and "Decimals" switches between the two modes.
The following examples show how to input equations.
Example 1. Solving the equation 
2x - 1.5 = 3x + 2
 
Example 2. Solving the  equation 
3.5 = 10x - 1
 
Example 3. Solving the equation 
4x + 5 = 3.5x
 
Example 4. Solving the equation
