n a football tournament, the Bees scored 9 less than three times as many points as the Hornets. The Wasps scored 28 more points than the Hornets. Together the three teams scored 184 points. Let x represent the number of points scored by the Hornets.
Translate the scenario.
Hornets = x
(Bees:x+28) (Wasp: 3x-9) (Equation: 4x- 20+3x=184
(Bees:3x-9) (Wasp: x+28) (Equation: 4x- 20+3x=184
(Bees:3x-9) (Wasp: x+28) (Equation: x+(3x-9)+(x+28)=184
(Bees:3x-9) (Wasp: x+28) (Equation:(3x-9)+(x+28)=184
