I need help with 9, 10 would be nice as well. But I’ll take what I can get :)

or, 3x = 5x-6

or, 6 = 5x - 3x

or, 6 = 2x

or, x = 6 ÷ 2 = 3

= 3x

= 3(3)

= 9 units

= XA + AY

= 3x + (5x-6)

= 8x-6

= 8(3)-6

= 24-6

= 18

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

boxplot e is the answer
