Question

A) 2/x = 3/x-1
b)4/x+1 = 5/x
c)3/5 = 2x-1/2-5x
d)2x+1/1-2x = 2/3

Answer 1

A) 2/x = 3/x-1 /*x
2=3-x
x=3-2
x=1

b)4/x+1 = 5/x /*x
4+x=5
x=5-4
x=1

c)3/5 = 2x-1/2-5x /*10
6=20x-5-50x
30x=-11
x=-11/30

d)2x+1/1-2x = 2/3 *3
6x+3-6x=2
0x=-1

Answer 2

A) 2/x = 3/x-1 /*(x-1)
2(x-1)/x=3
2x-2/x=3 /*x
2x-2=3x
x=-2
b)4/x+1 = 5/x *(x+1)
4=5(x+1)/x /*x
4x=5x+5
-x=5 /:(-1)
x=-5
c)3/5 = 2x-1/2-5x /*5
3=10x-5/2-5x /*(2-5x)
3(2-5x)=10x-5
6-15x=10x-5
6+5=10x+15x
11=25x /:11
x=2 i 4/11
d)2x+1/1-2x = 2/3 /*3
6x+3/1-2x=2 /*1-2x
6x+3=2(1-2x)
6x=2-4x-3
10x=-1 /:10
x=-0,1
