Write an equation to represent the sum modeled in the following number line.
hh i can't sleep without finishing this quiz and i literally can't think anymore but i need a good grade on it hkjdhkj

let x and y be two integers then this number line can be represented as linear equation with two variable

2x-3.1y= -1.1

here x and y could be 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:

22 dimes and 9 nickels
