Answer 1

Answer:

Step-by-step explanation: 9*2x - 5*2(x+2)= 4*45

                                              18x-10x -20 =180

                                                   8x= 200

                                                       x=25

Answer 2

Answer:

Question :-

2/5 x - 2x + 4/ 9 =4

Step-by-step explanation:

LCM is 45

Therefore,

(2x × 9 / 45) - 5 ( 2x +4)/ 45 = 4

18x - 10x - 20 / 45 = 4

8x - 20 / 45 = 4

Now, both sides same denominators i.e.. 45.

8x - 20 / 45 = 4 x 45 / 45

8x - 20 / 45 = 180 / 45

Same denominators is acquired so both of the denominators can be cancelled.

So,

8x - 20 = 180

8x = 180 + 20

8x = 220

x = 220 / 8

x = 25
