Find all values of c such that 3(2c + 1) = 28*(3c) - 9 + 45(3c) - 18. If you find more than one value of c, then list your values in increasing order, separated by commas.
3(2c + 1) = 28*(3c) - 9 + 45(3c) - 18
6c + 3 = 84c – 9 + 135c – 18
6c – 84c – 135c = – 3 – 9 – 18
– 213c = – 30
c = – 30 / – 213 = 30 / 213 reduces to 10 / 71
