47 = 2(x + 3) + 3(x - 3)

47 = 2x + 6 + 3x + - 9

47 =(2 x + 3x) + (6 + - 9)

47 = 5x + - 3

47 = 5x - 3

5x - 3 = 47

5x = 47 + 3

5x = 50

$x = \frac{50}{10}$

x = 10

Let us check whether or not we have found out the correct value of x by placing 10 in the place of x .

So :-

47 = 2(10 + 3) + 3(10 - 3)

47 = (20 + 6) + (30 - 9)

47 = 26 + 21

47 = 47

LHS = RHS

As the left hand side of the equation is equal to the right hand side of the equation , we have found out the correct value of x .

Therefore , 47 = 2 ( 10 + 3 ) + 3 ( 10 - 3 ) and x = 10 .
