Distribute
a(b+c)=ab+ac
2(10-r)=20-2r
now we have

Don’t do that it’s a scam and a virus
Hi, thank you for posting your question.
This problem can be solved through ratio and proportion which can be applied to similar triangles like that shown in the figure. By ratio and proprotion,
MP/MN = MB/MA
81.9/67.2 = x/(67.2-32)
Thus, x = 42.9
