3.After inputting the last coefficient, press e to solve the 2-VLE.

•After solving, press e or j to return to the coefficient entering display. You can use @ h to solve the 2- VLE, regardless of the cursor position.

x=	–1.
y=	2.
D=	–3.

Example 2

x+y-z= 9	x = ?
6x+6y-z= 17	Ò y = ?
14x-7y+2z= 42	z = ?
	det(D) = ?

1.Press b 3 1 to select 3- VLE of the EQN mode.

2.Enter the value of each coefficient (a1, etc.)
