Question

x/4-x/6=3, 3x/4-x/3=5, x/5-1=9, x/3-5=0, x/2+3x/5=6, x/5+x/2=7/10

Answer 1

x/4-x/6=3   mmc= 12
3x - 2x = 36
  x = 36
 
3x/4-x/3=5, mmc=12

9x - 4x = 60
5x = 60
  x = 12

x/5-1=9   mmc= 5
x - 5 = 45
x = 45+5
x=50

x/3-5=0  mmc= 3

x - 15=0
x = 15






x/2+3x/5=6        mmc= 10
5x+6x = 60
     11x = 60
        x = 60/11

x/5+x/2=7/10         mmc = 10

2x+5x = 7
 7x = 7
   x= 1
