u eliminate (elim)

Function: Assigns an expression to a variable.

Syntax: eliminate( {Eq/Ineq} -1, variable, Eq-2 [ ) ]

○ ○ ○ ○ ○

Example

To transform Y = 2X + 3 to X= and then substitute 2X + 3Y = 5

3(EQUA)g(elim)ca+(X)+da-(Y)!.(=)

f,

a+(X),a-(Y)!.(=)

c

a+(X)+dw

4Y – 3 = 5

u getRight (getRgt)
