2x + 5y = 270
Two times the amount of wheeled backpacks. Let x = wheeled backpacks.
Five times the amount of non wheeled backpacks. Let y = non wheeled backpacks.
Total backpacks will be 330 so 330 - 60 = 270
Therefore you get 2x + 5y = 270
Step-by-step explanation:
you can simply multiply things out.
4/9 × y = 8/3
4y = 9×8/3 = 3×8 = 24
y = 6
or you could have transformed the right hand side into a fraction of the same denominator (9) :
8/3 = 8/3 × 3/3 = (8×3)/(3×3) = 24/9
4/9 × y = 24/9
that means 4y = 24
y = 6
