47 = 2(x + 3) + 3(x - 3)
what's the answer to this ?

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

So :-

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 .
