Which statement is correct by observing (12x+5y=41) and (24x+10y=82)?

Answer and explanation

Correct answer: Lines are the same

The second equation is exactly twice the first: 24x+10y=2(12x+5y) and 82=2×41. Therefore, both equations represent the same line and the pair has infinitely many solutions. Option A would be correct if the ratios of the coefficients of x and y were equal but the ratio of the constants were different. In an exam, compare a₁/a₂, b₁/b₂, and c₁/c₂ to determine the position of the lines.
