Answer:

The value of x is 2

Step-by-step explanation:

Given expression as :

5 [ 3 (x + 4) - 2 (1 - x) ] - x - 15 = 14 x + 55

Or , 5 [ 3 x + 12 - 2 + 2 x ]  - x - 15 = 14 x + 55

Or, 5 [ 5 x + 10 ] - x - 15 = 14 x + 55

Or, 25 x + 50 - x - 15 = 14 x + 55

Or , 24 x + 35 = 14 x + 55

Or, 24 x - 14 x = 55 - 35

Or, 10 x = 20

∴  x = [tex]\frac{20}{10}[/tex] = 2

Hence The value of x is 2  . Answer
