Press 6(AUTO) to enter the Auto Mode.

In the Simultaneous Equation Mode, you must also select SBSTIT (Substitution Method) or

ADD-SU (Addition/Subtraction Method).

The Substitution Method first transforms the equation to the format Y = aX + b, and

substitutes the other expression to Y.*

The Addition/Subtraction Method multiplies both sides of the expression by the same value

to isolate the coefficient X (or Y).

As with the Algebra Mode, the screen is divided between an input area and a display area.

Each press of 6(NEXT) advances to the next step. 6(NEXT) is not shown on the display

when after the solution is obtained.

You can scroll back through the steps by pressing 1(BACK).

Example To solve 4X = 8 in the Auto Mode
