+1000 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.
+1952 First, let's simplfy the equation a bit. Distributing and expanding, we get
6c+3=84c−9+135c−18
Isolating c and combining even more like terms, we get
−213c=−30
Now, we simply isolate c, and we get
−213c−213=−30−213
c=1071
So our final answer is 10/71.
Thanks! :)
