Question

73.5²+5².28-5²

5x+5³=1010

2727:(158-x)=27

Answer 1

73.5²+5².28-5²

=5².(73+28-1)

=5².100

=25.100

=2500

5x+5³=1010

5x+125=1010

5x=1010-125

5x=885

x=885:5

x=177

2727:(158-x)=27

158-x=2727:27

158-x=101

x=158-101

x=57

Answer 2

5x + 125 = 1010

        5x  = 1010 - 125

        5x  = 885

          x  = 885 : 5

          x  = 177
