The following equation is transformed into the form where y is represented by the algebraic expression containing x, and then transformed into the form where x is represented by the algebraic expression containing y （1） 2X+5Y=10 （2） X-2Y-6=0

The following equation is transformed into the form where y is represented by the algebraic expression containing x, and then transformed into the form where x is represented by the algebraic expression containing y （1） 2X+5Y=10 （2） X-2Y-6=0

(1) Algebraic expression y with X
Y=(10-2X)/5=2-2X/5
Algebraic expression x with y
X=(10-5Y)/2=5-5Y/2
(2) Algebraic expression y with X
Y=(X-6)/2=X/2-3
Algebraic expression x with y
X=6+2Y

（5x^2y^3-4x^3y^2+6x)/(6x)
.(1/3x^3m*y^2n-x^2m-1*y^2+3/4x^2m+1*y^3)/(-0.5x^2m-1*y^2)

（5x^2y^3-4x^3y^2+6x)/(6x)
=5x^2y^3/(6x)-4x^3y^2/(6x)+6x/(6x)
=5xy^3/6-2x^2y^2/3+1

(5x^2+6x-7)+[-4x^2-( )] =x^2+2x+1 （x^3-4x^2y+11xy^2-y^3）+（）=x^3+3x^2y-5xy^2

(5x^2+6x-7)+[-4x^2-(4x-8 )] =x^2+2x+1
（x^3-4x^2y+11xy^2-y^3）+（7x^y-16xy^2+y^3）=x^3+3x^2y-5xy^2
