Comparing coefficients tells us the graph type. For 3x + 2y = 7 and 6x + 4y = 9, check the ratios a1/a2, b1/b2, c1/c2 and decide the number of solutions.

Question

Accepted Answer

No solution (parallel lines). a_1/a_2 = 3/6 = 1/2, b_1/b_2 = 2/4 = 1/2, c_1/c_2 = 7/9. Since a_1/a_2 = b_1/b_2 ≠ c_1/c_2, the lines are parallel: no solution.
