Which conclusion is correct by observing the equations (12x+16y=36) and (3x+4y=11)?

Answer and explanation

Correct answer: The first two ratios are equal, but the ratio of the constant terms is different

Here, 12/3=4 and 16/4=4, so the ratios of the coefficients of x and y are equal. However, 36/11 is not equal to 4. Thus, a₁/a₂=b₁/b₂≠c₁/c₂, so the two lines are distinct and parallel and the pair has no solution. Exam tip: In this case, the lines have equal slopes but do not intersect.
