Solve for x:
`16/x-1=15/(x+1);x!=0,-1`
उत्तर
Given :
`16/x-1=15/(x+1);x!=0,-1`
`(16-x)/x=15/(x+1)`
`(16-x)(x+1)=15x`
`16x+16-x^2-x=15x`
`16=x^2`
`x=4`

Complete the following activity to solve the given word problem. The Sum of squares of two consecutive even natural numbers is 244, then find those numbers.
Activity: Let the first even natural number be x
Therefore its consecutive even natural number will be = (______)
By the given condition,
x2 + (x + 2)2 = 244
x2 + x2 + 4x + 4 – (______) = 0
2x2 + 4x – 240 = 0
x2 + 2x – 120 = 0
x2 + (______) – (______) – 120 = 0
x(x + 12) – (______) (x + 12) = 0
(x + 12)(x – 10) = 0
x = (______)/x = 10
But natural number cannot be negative, x = – 12 is not possible.
Therefore first even natural number is x = 10.
Second even consecutive natural number = x + 2 = 10 + 2 = 12.
