Question

So my teacher teach us about this leason but I did not understand it at all can someone please teach me.

Answer 1

x + 2= 2(2x - 14 )

We will first find x

x + 2 = 4x - 28

collect like term

4x - x = 28 + 2

3x = 30

Divide both-side of the equation by 3

x = 10

But TU = 2x - 14

substitute x = 10 in the above and evaluate

TU = 2(10) - 14 = 20 - 14 = 6

Hence the length of TU is 6
