1. The sum of three numbers is 301. The second number is 3 less than twelve times the first number. The third number is 4 more than seven times the number. Find the three numbers.

2. Two friends live 15 miles apart. One day they decide to jog and meet each other. Tanya leaves her house and heads east, jogging at a rate of 2.5 miles per hour. At the same time Kelly leaves her house and heads west, jogging at a rate of 3.5 miles per hour. How long does it take for the two friends to meet?
Please help me out with these word problems. Thanks a lot!

1. First number = x, second number = 12x  3, and if the third number is being compared to the first, it = 7x + 4. The sum of these = 301. Solve for x.
2. 15 = 2.5x + 3.5x
Solve for x.
I hope this helps. Thanks for asking.
