Solve for x please... it's for a test and it's really hard I'll give you all my points, thanks
4(x - 1) - 3 (x - 2) = - 8

answer: (1,3) and (-2,0) i think.

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

its kinda hard to answer this when we dont have all the information that we need.
