An equivalent to 3x+3(5x-18)=108 would be 3x + 15x - 54 = 108, after multiplication on 3(5x-18). This, in turn, would be 18x = 162, whose solution is 9.
Hey there!!
The given equation :
... 3x + 3 ( 5x - 18 ) = 108
... 3x + 15x - 54 = 108
... 18x - 54 = 108
... 18 x = 162
This is equivalent to the above question.
... The solution would be 162 / 18 = 9
Hope my answer helps!!
