Answer

infinite number of solutions

Work Step by Step

Write the first equation as a solution for x: -x + 2y = 3 2y - 3 = x Insert the equation for x in terms of y in the second equation: 3(2y - 3) - 6y = -9 6y - 9 - 6y = -9 -9 = -9 The statement is always true, so there is an infinite number of solutions.
