4n = 3n + 4
4n - 3n = 3n - 3n + 4
n = 4
check:
4n = 3n + 4
4(4) =? 3(4) + 4
16 =? 12 + 4
16 = 16 True
7x - 8 = -297x - 8 + 8 = -29 + 87x = -217x/7 = -21/7x = -3

It is: 48/10 = 4.8
Thirty decreased by three times a number is six less than three times the number. Find the number.
5(x+3)+8
Twenty more than twice a number is 52
7x - 8 = -297x - 8 + 8 = -29 + 87x = -217x/7 = -21/7x = -3
