We have ax - bx = 1;
Then (a - b)x = 1;
If a - b is not 0, then x = 1 / (a-b);
Answer:
7/12 cannot be reduced
Step-by-step explanation:

Jon and Gina are different we’re opposite
The sum of their speeds is 380 miles per hour. The difference of their speeds is 30 miles per hour. Then the faster plane is traveling at
.. (380 +30)/2 = 205 miles per hour
The slower plane's speed is 30 miles per hour less, so it is traveling at
.. 205 mph -30 mph = 175 miles per hour
