Q1)  u+2=4     subtract 2 from both sides

 

u  = 2

 

 

 

Q2)   6= x+2/3       multiply through by 3

 

18  = 3x  + 2   subtract 2 form both sides

 

16  =  3x      divide both sides by 3

 

16 / 3  = x

 

 

 

Q3)   13+w/7=18   multiply through by 7

 

91  + w =  126       subtract 91 from both sides

 

w  =  35

 

 

 

 

Q4)    17= -13-8x      add13 to both sides

 

30  =  -8x     divide both sides by -8

 

30 / -8   =   15 / -4   =  x
