Question

Sa se exprime x in functie de y in urmatoarele situatii:
a) 2x-3y=o
b) 4x-y=5
c) 3(x-2y)+x=y
d) 3-2(x-2y)=x
e) xy+2x=3y
f) 2x+y=xy
g) 2xy-3y=2x+1
h) x+2/3y=x+3/4

Daca cineva poate sa faca asta rapid pentru mine primeste coroana!!!!

Answer 1

a) 2x-3y=0

2x=3y

x=3y/2

b)4x-y=5

4x=5+y

x=(5+y)/4

c)3x-6y+x=y

4x=7y

X=7y/4

d)3-2x+4y=x

3+4y=3x

x=(3+4y)/3

e)xy+2x=3y

x(y+2)=3y

x=3y/(y+2)
