Answer:

for 18 x is 6 and for 20 it is 11

Step-by-step explanation:

For 18, since -1+2x and 5+x is the same thing, set up and equation. WE can simplify to -1+x=5 and then we get x=6

For 20, 18 is 11 since 18=-4+2x. If we simplify we get 22=2x then we can use algebra to say that x=11

Hope this helps :)

Answer:

18.) x = 6

20.) x = 11

Step-by-step explanation:

<em><u>18.)</u></em>

We know that line segments FC and ED are parallel to each other so they are congruent to each other:

-1 + 2x = 5 + x

-1 + x = 5

<u>x = 6</u>

<u><em>20.)</em></u>

We know that line segments DE and CF are parallel to each other so they are congruent to each other:

18 = -4 + 2x

22 = 2x

22/2 = x

<u>11 = x</u>

Hope this helps!
