Question

Solve 2/5x = -3/15 + 1/x

Answer 1

the options are
1)
x = 3

2)
x = 0

3)
x = 5

4)
x = 15

Answer 2

\[ \frac { 2} { 5x} = \frac { -3}{ 15} + \frac { 1} { x} \\ (5x)\frac { 2} { 5x} =(5x) \frac { -3}{ 15} + (5x) \frac { 1} { x} \\ 2 = -x + 5\\ x= 3\]

Answer 3

2/5x=-3/15+1/x
put 1/x=y
2y/5=-3/15+y
6y=-3+15y
15y-6y=3
9y=3
y=3/9=1/3
1/x=1/3
x=3

Answer 4

ok thanks
