document.write( "Question 667029: Hey, my name is Michelle. I need to find out what the variable is in the question 7c-2/3=1/2 I already know that c=1/6 but I need to solve it the way my teacher said. The way that she taught us is when you have something that subtracts to cancel it out, you add on both sides. When you do that with this problem, you end up with 7c=7/6 if you solve it. From there, usually you would divide the 7 by 7 to cancel it out (you put the 7 under the other 7 like a fraction 7/7), but since you can't just divide a fraction under a fraction I'm stuck. Please help me, please and thank you. \n" ); document.write( "
