Question

solve the following:|x-7|=8

Answer 1

either x-7=8
=>x=15
or; x-7=-8
=>x=-1

Answer 2

Answer:

x=15 and x= -1

Step-by-step explanation:

|x-7|=8

split into two equations for positive and negative side.

x-7=8        and    x-7=-8

solve each equation individually with +7

x - 7 = 8        and    x - 7 = -8

  +7  =+7                     +7=+7

 x     =15                  x      = -1

so x = 15 and -1
