The 3 lines x = 3, y – 2.5 =-(x – 0.5), and y – 2,5 = x – 3.5 intersect at point P. Find the coordinates of P. Verify algebraically that the lines all intersect at P.

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:

good luck on your studies! : )
