Answer 2

Answer:

a) - 7

b) 8

Step-by-step explanation:

2 ( x + 4 ) = 3( x + 5)

2x + 4 *2 = 3x + 5*3

2x + 8 = 3x + 15

8 - 15 = 3x - 2x

- 7 = x

Let the number be ' x '

Thrice the number will be 3*x = 3x

Then the equation will be

3x + 6 = 30 ( AS PER THE QUESTION )

3x = 30 - 6

3x = 24

x = 24/3

x = 8
