Which of these strategies would eliminate a variable in the system of equations? 8x + 8y = 2
8x + 5y = 1

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:

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

the ratios are reciprocals im positive

step-by-step explanation:

they are all positive numbers so it wouldn't be the other ones

77
