What's the answer to this problem?

no real solutions

Step-by-step explanation:

- Rewrite equations:

y=3x−11;−3x+y=−13

Step: Solvey=3x−11 for y:

y=3x−11

Step: Substitute 3x−11 for y in−3x+y=−13:

−3x+y=−13

−3x+3x−11=−13

−11=−13(Simplify both sides of the equation)

−11+11=−13+11(Add 11 to both sides)

0=−2

No solutions.

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
