ABSOLUTE VALUE 1


If │2x + 11│= 47; Find  x

Solution

±(2x + 11 )= 47
  
2x +11= 47    OR   –(2x+11) = 47
  
2x+ 11 = 47    OR   -2x - 11=47

2x = 47- 11    OR   -2x= 47 + 11

2x = 36     OR     -2x  =  58
2       2                 -2       -2

x = 18  OR  x = -58/2 = -29

Hence,  x = 18 OR  x = -29 

TRY THIS...............................


If │2x + 19│= 37; Find  x
