Question

value of 'x' in 1/3+'x'=2/5​

Answer 1

Answer:

Value of x is 1/15

Step-by-step explanation:

1/3+x=2/5

= x=2/5-1/3

= after taking LCM, we get,

= x= (6-5)/15

therefore, x=1/15.

Answer 2

Step-by-step explanation:

$\frac{1}{3 + x} = \frac{2}{5}$

using Cross multiplication

5 × 1 = 2(3+×)

5 = 6+2x

2x = 5 - 6

2x = -1

x = - 1/2
