2.

20 pounds of strawberries

5 pounds per person

20 ÷ 5 = 20 pounds ÷ 5 pounds/person= 4 persons

4 is the number of people we're splitting among

y - y1 = m(x- x1)

y - (-5) = 2/3(x -0)

y + 5 = 2/3x

y = 2/3x - 5

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:
