12x+6y= 24

Move +6y to the other side. Sign changes from +6y to -6y

12x+6y-6y= 24-6y

12x= 24-6y

divide by 12

12x/12= 24/12-6y/12

x= 2-1/2y

Answer: Od. x=2-1/2y

denis23 [38]

Answer:

The total distance they will travel on their trip is 308 miles.

Step-by-step explanation:

This question can be solved using a rule of three.

114 miles is 37% = 0.37. How many mines are 100% = 1?

114 miles - 0.37

x miles - 1

0.37x = 114

x = \frac{114}{0.37}

x = 308.11

Rounding to the nearest mile

The total distance they will travel on their trip is 308 miles.
