Question

The sum of 5/2 and 6 times a number equals to 7/2 subtracted from seven times the number find the number

Answer 1

1 / 13

Explanation:

lets just say the number is 'x'

5/2 + 6x = 7/2 - 7x

6x + 7x = 7/2 - 5/2

13x = 2/2

13x = 1

x = 1/13

proving it

5/2 + 6 × 1/13 = 7/2 - 7 × 1/13

5/2 + 6/13 = 7/2 - 7/13, solving the fraction by finding the L.C.M will result in

77/26 = 77/26
