Question

17( 2 - x ) upon 1 - 7x + 5 ( x + 12 ) upon 7x -1 = 8

Class 8, Maths chapter 8, EX. 8.2 Q8​

Answer 1

Answer:

x = 1

Step-by-step explanation:

8.

[17(2 - x)/1 - 7x]  +  [5(x + 12)/7x - 1)] = 8

=> [17(2 - x)/1 - 7x] - [5(x + 12)/1 - 7x] = 8

Here, the denominator is same.

=> (34 - 17x - 5x - 60)/(1 - 7x) = 8

=> (-22x - 26) = 8(1 - 7x)

=> -22x - 26 = 8 - 56x

=> 34x = 34

=> x = 1

Hence, the value of x = 1.
