¿Cómo usar?
- La ecuación:
-
Ecuación (|x|)=6
-
Ecuación z^4+4=0
-
Ecuación x-32/4=50
-
Ecuación x*40+3800=6400
- Expresar {x} en función de y en la ecuación:
- 12*x+8*y=18
- 8*x+6*y=20
- -2*x+18*y=13
- -11*x-1*y=15
-
Expresiones idénticas
- (x- tres)/(x+ dos)+(x+ ocho)/(x- uno)=(quince)/x+ dos *(x- uno)
- (x menos 3) dividir por (x más 2) más (x más 8) dividir por (x menos 1) es igual a (15) dividir por x más 2 multiplicar por (x menos 1)
- (x menos tres) dividir por (x más dos) más (x más ocho) dividir por (x menos uno) es igual a (quince) dividir por x más dos multiplicar por (x menos uno)
- (x-3)/(x+2)+(x+8)/(x-1)=(15)/x+2(x-1)
- x-3/x+2+x+8/x-1=15/x+2x-1
- (x-3) dividir por (x+2)+(x+8) dividir por (x-1)=(15) dividir por x+2*(x-1)
