1)9x +28=2755
2) 510+14x=762
3)5x-97=934

Answer 1

1) 9x +28= 2755 => 9x= 2755-28 => 9x = 2727 => x=303
2) 510 + 14x= 762 => 14 x = 252 => x= 18
3) 5x -97= 934 => 5x = 934 +97 => 5x= 1031 => x= 1031/5

Answer 2

1) 9x=2755-28⇔9x=2727⇔x=2727÷9⇔x=303
2)14x=762-510⇔14x=252⇔x=252÷14⇔x=18
3)5x=934+97⇔5x=1031⇔x=1031÷5⇔x=206.2
