Answer:
(d)
Step-by-step explanation:
Equation A has infinitely many different solutions. That is, there are infinitely many different values for x and y that make the equation a true statement. For example, x = 1 and y = 4 is one such solution.
Likewise, equation B has infinitely many different solutions.
But we want a solution for both equations simultaneously. This is a value for x and a value for y that makes both equations true at the same time.
So "y" in equation A is to be the same as "y" in equation B, which means that the -x+5 in equation A will be equal to the 6x-2 in equation B.
I.e. -x + 5 = 6x - 2
