Question

3x-2/10-x+3/7+4x-7/3=x-1

Answer 1

Hey
Here's your answer !!


3x-2/10 - x+3/7 + 4x-7/3 = x-1

Now , L.C.M. of 10 , 7 and 3 is 210 .

So, { (3x-2) * 21 / 10 * 21 } + { (x+3) * 30 / 7 * 30 } + { (4x-7) * 70 / 3 * 70 } = x - 1 .

=> ( 63x - 42 / 210 ) + ( 30x + 90 / 210 ) + ( 280x + 210 ) = x - 1 .

=> 373x + 258 / 210 = x - 1 .

=> 373x + 258 = 210 ( x - 1 ) .

=> 373x + 258 = 210x - 210 .

=> 163x = 48

=> x = 48 / 163 .

=> x = 0.29 . [ Answer ] .

Hope it helps !!
