Question

IF 5x/3-4=2x/5= then the numerical value of 2x-7 is?
(A) 19/13. (B)-13/19
(C)0. ( D) 13/19​

Answer 1

Answer:

13/19

Step-by-step explanation:

(5*/3)-4=2*/5

(5*/3)-(2*/5)=4

(25x-6x)/15=4

19x=15*4

x=60/19

hence

2x-7

2(60/19)-7

(120/19)-7

(120-133)/19

13/19

Answer 2

Answer:

5x/3 - 4 = 2x/5

5x/3 - 2x/5 = 4

Taking LCM,

(25x - 6x)/15 = 4

25x - 6x = 60

19x = 60

x = 60/19.

------------------------------

2x - 7

= 2(60/19) - 7

= 120/19 - 7

= 6.315... - 7

= -0.684....
