Answer 1

Answer:

x = (-45/52)

Step-by-step explanation:

Taking LCM

(8x-45)/20 = 3x

Multiplying by 20 on both sides

(8x-45) = 60x

52x = -45

Hence, x = (-45/52)

Answer 2

Step-by-step explanation:

2x/5 - 9/4 = 3x

lcm of 5,4 is 20

8x/20 - 45/20 = 3x

8x - 45 / 20 = 3x

8x - 45 = 60x

-45 = 52x

x = -45/52
