Solve the simultaneous equations 3x=2y and 2xy=12

Answer:x=-2, y=-3 or x=2, y=3
Explanation:We can rewrite 2xy=12 as (2y)x=12, and since we know that 2y=3x, we can substitute this in to get the following equation: 3x^2 = 12. Solving this we get that x=2 or x=-2, and subbing into 2y=3x, we get the corresponding y values of y=3 or y=-3
