Solve 1.25x + 1.50y = 28.25.

Step-by-step explanation:

Assuming you are solving for the intercepts.

for x you set y to 0.

28.25 = 1.25x

divide by 1.25 on both sides.

you get 22.6

for y you set x to 0

28.25 = 1.5y

divide by 1.5

you get 18.83 repeating

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:
