the answer is 9.75 the steps are.... first simplify both sides so... −1.6(2c+12)=12(−1.6)(2c)+(−1.6)(12)=12(Distribute)−3.2c+−19.2=12−3.2c−19.2=12 then add 19.2 to both sides because your trying to get the c by itself.. −3.2c−19.2+19.2=12+19.2−3.2c=31.2 and then finally divides both sides by -3.2 so that c will be by itself AND THEN..you get 9.75
