Remark
You should always write proportions the way you normally do first. Most people write a proportion as
4/20 = 2 / 10 Using colons helps to make clear what is comparred all on one line.
4:20::2:10
:: is the equal sign
/ is the division sign.
: (a single colon) takes the place of /
9/27 = 2 / 6
Which can be
9:27::2:6
Note
The colon method is not in current use as much as it was.
All you need to do to solve this is multiply 2 to both sides. This will cancel out 2 from the denominator and isolate x...
2() = -7 * 2
x = -14
Hope this helped!
