Question

Q.20 The value of x in (x +7)/(3x + 16) = 4/7
.is​

Answer 1

Answer:

-3

Step-by-step explanation:

(x+7)7=(3x+16)4

7x+49=12x+64

7x-12x=64-49

-5x=15

x= -15/5

x= -3

Answer 2

x + 7x/3 + 16= 4/7

10x/3 + 16 = 4/7 (on finding the lcm)

10x/3 = 4/7 - 16

10x/3 = -108/7

70x = -324

x= - 324/70

= 162/35
