Best ResponseYou've already chosen the best response.05c  9 = 8  2c ... we want to get the c terms on one side and everything else on the other side...and what you do on one side of the equal sign, you have to do on the other side. So first we will add 2c to both sides 5c  9 + 2c = 8  2c + 2c  now we combine like terms 7c  9 = 8 ...see how the 2c's on the right side cancelled out now we will add 9 to both sides 7c  9 +9 = 8 + 9  combine like terms 7c = 17....now we need c by itself, so we divide both sides by 7 (7/7)c = 17/7....the 7/7 turns into 1 and 1c is just c.... so c = 17/7 or in decimal form = 2.43
