SOLVE THIS 7(y - 5) + 3y = 10(y +1)

No solution

Step-by-step explanation:

7(y - 5) + 3y = 10(y +1)

7y - 35 + 3y = 10y + 10

10y - 35 = 10y + 10

10y - 10y = 10 + 35

0 = 45

This is No Solution

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

inverse property is the answer
