What is the correct conclusion by observing the equations (16x-12y=44) and (4x-3y=12)?

Answer and explanation

Correct answer: No solution

Dividing the first equation by 4 gives \(4x-3y=11\), whereas the second equation is \(4x-3y=12\). The ratios of the coefficients of \(x\) and \(y\) are equal, but the ratio of the constant terms is different: \(16/4=(-12)/(-3)=4\), while \(44/12=11/3\). Hence, the two lines are parallel and distinct, so they have no common solution. Option C would be correct only if all three ratios were equal. Exam tip: if \(a_1/a_2=b_1/b_2\ne c_1/c_2\), the pair of linear equations is inconsistent and has no solution.
