1. seven times the sum of a number and three is six less than ten times the number.
Solution:

seven times the sum of a number and three = 7(x + 3)
six less than ten times the number = 10x - 6
So 7(x + 3) = 10x - 6

2. if four is subtracted from three times a number, the result is ten more than the number
3x - 4 = 10 + x

Hope this helps
