15x - 60 -2x -6 -3x -24 = 0
15x - 3x - 2x - 60 - 6 - 24 = 0
15x-5x - 60 - 30=0
=> 10x - 90 =0
[ adding 90 to both sides]
=> 10x - 90 + 90 = 0 + 90
=> 10x = 90
=> x = 90/10 = 9 ..answer...
Now,
placing x = 9 in the equation we get...
15(9-4) - 2(9+3) - 3(9+8) =0
=> 15(5) - 2(12) - 3(17) = 0
=> 75 - 24 - 51 = 0
=> 75 - 75 = 0
checked!..
Hope it helps ....
Thank u !!..☺️☺️✌
