Andrea says that a system of two linear equations must have at least one solution as long as the lines have different y- intercepts. for example, the equations y =2x+4 and y=4x-6 have different y-intercepts and have a solution at (5,14). select the pair of linear equations that can be used to disprove andrea's claim.

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
