Given:\\\overline{DE}=4X-1\\\overline{EF}=9\\\overline{DF}=9x-22\\\\\overline{DF} \; is \; a \; line \; segment,  \; E \; is  \; a \; point \; in  \; between.\\\\So,\; \overline{DE}+\overline{EF}=\overline{DF}\\4x-1+9=9x-22\\Subtract \; 9x \; on \; both \; sides\\\\4x-9x-1+9=9x-9x-22\\Combine \; like \; terms \; on \; both \; sides\\\\-5x+8=-22\\Subtract \; 8 \; on \; both \; sides\\\\-5x+8-8=-22-8\\-5x=-30\\Divide \; -5 \; on \; both \; sides\\\\\frac{-5x}{-5}=\frac{-30}{-5}\\x=6

How do I work this out oof
kakasveta [241]

I am so sorry for giving you the wrong answer at first.

Here's the processs

1x=-0.5555

Move the decimal point in the repeating decimal one space forward

10x=-5.55555

Then subtract

10x=5.5555

x=-0.5555= 9x=-5

Divide both sides by 9

9x=-5

9x/9=-5/9

-5/9 is your final answer!

Hope this helps!
