Answer 1

Answer:

I think d is correct

means 13/19

Answer 2

Answer:

-13/19

Step-by-step explanation:

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

Or, (5x-12)/3=2x/5. (LCM)

after cross multiplying,

Or, 25x-60=6x

Or, 19x=60

Or, x=60/19

Now,

2x-7

putting the value of x,

2(60/19)-7

Or, (120/19)-7

Or, (120-133)/19. (did LCM )

Or, -13/19
