ALGEBRA H4

If │2x – 7 │= 37; Find  x

 

Solution

 

±(2x – 11 )= 37

 

2x -11= 37    OR   –(2x-11) = 37

 

2x – 11 = 37    OR   -2x+11=37

 

2x = 37 + 11    OR   -2x= 37-11

 

2x = 48     OR   -2x  =   26

2      2               -2        -2

 

x = 24  OR  x = -13

 

 

Hence x = 14 OR x = -3

 

TRY THIS……………………….
