Answer:
Step-by-step explanation:
Part 1: 2x + 5 / 2x + 5 + 7 = 3 [Then we are going to do cross multiplication]
=> 2x + 5 = 6x + 15 +21 [We, are going to this equation]
=> 6x + 15 + 21 = 2x + 5 [Solving for x]
=> 4x = - 21 - 10 [Keeping x on L.H.S]
∴ 4x = - 11 [ So, first we had found a solution for, x]
Part 2: 2x + 5 + 7 / 2x + 5 = 3 [So, are going to do the, as the first equation]
=> 2x + 5 + 7 = 6x + 5
=> 6x + 5 = 2x + 5 + 7
=> 4x = 7 + 5 - 5
∴ 4x = 7
[ So, from part 1 ,we get X = 11 / 4, and from part 2, we get X = 7 / 4
∴ X is either 11 / 4 or 7 / 4]
