Is 7x plus 2y equals 16 and -21x-6y equals 24 a no solution?

Where does y equals 3x-5 and 21x-35 equals 7y intersect on a graph?

put both equations in standard form y - 3x = -5 (equation 1) -7y + 21x = 35 (equation 2) multiply equation 1 by 7 (this is done so either one of your variables will cancel... if both variables cancel then these lines are parallel) 7y - 21x = -35 -7y + 21x = 35 0 = 0 therefore your lines are parallel
