Question

solve the equation and verify your answer.
1)7x/9=21
2)p/3-p/4=1
3)2a/3-a/2=-30
4)4x/3=7-x

Please answer it very very urgent ​

Answer 1

Step-by-step explanation:

1. 7x/9=21

= 7x = 21×9

= 7x = 189

= x = 189/7

= x = 27

2. p/3-p/4=1

= LCM of 3 and 4 is 12

= 4p-3p/12 = 1

= p/12 = 1

= p = 12

3. 2a/3-a/2=-30

= LCM of 3 and 2 is 6

= 4a-3a/6 = -30

= a/6 = -30

= a = -30×6

= a = -180

4. 4x/3=7-x

= 4x = 3(7-x)

= 4x = 21-3x

= 4x+3x = 21

= 7x = 21

= x = 21/7

= x = 3
