Is x equals 1 and y equals -4 a solution to the following equation y equals -2x?
No. -4 does not equal -2(1).
What is the solution to the system 2x-y equals 2 2x-y equals -2?
2x - y = 2 2x - y = -2 This system is inconsistent -- that is, there is no solution. To help see why, let Z = 2x - y and notice Z can't be 2 and -2 at the same time.
Why does 2x-3 equals 2x-5 have no solution?
2x - 3 = 2x - 52x = 2x - 22x - 2x = -20 =/= -2Zero is not equal to -2 so the answer is no solution.
