What is  43c + 8c = 9?
550665
43c+8c equals 53c\nso 53c=9\ndivide both sides by 53 to get \nc=0.1698113

Go for it... ask some questions and I'll try and help.  However, be forewarned, I like to give people the *method* to solve a problem, so they can do it later on their own.  You will rarely find me just giving out answers.  Hope that is okay.\n\nIn your example:\n64 - 40ab\n\nThe best you can do is factor out a common factor from 64 and 40.  Both of these numbers are divisible by 8 (8 x 8 and 8 x 5)... that means you get:\n\n8(8 - 5ab)\n\nSince 8 and 5 share no further common factors, you can't factor them any further.  Also, a and b are only part of the second number, so you can't factor those...  the answer is:\n8(8 - 5ab)

12x - 16y = 8\n9x - 12y = 6\n\n12x - 16y = 8\n-16y = -12x + 8\ny = (3/4)x - (1/2)\n\n9x - 12y = 6\n-12y = -9x + 6\ny = (3/4)x - (1/2)\n\nANS : 3.) (t,(3/4)t - (1/2))\n\nThats if i understand you correctly.

by solving the two equations we get their point of intersetion...... we get the limits from -sqrt c to + sqrt c\n\nso int(c-x^2)dx - int ( x^2-c) = 9\n\nwe get (8c sqrt c)/3 = 9\n\nsolving we get c^3 = 729 / 64\n\nthat means c = 9/4
