Is the system linear equations 2x + 3y -9 = 0 and 4x + 6y – 18 = 0 consistent? Justfy your answer

Question

Mackenzie · Answer

Answer:   Your answer is here:-   Step-by-step explanation:   2x + 3y - 9 = 0    A1 = 1,  B1= 3,  C1 = -9     4x + 6y - 18 = 0    A2= 4, B2=6, C2 = -18    A1/A2  = 2/4 = 2   B1/B2  = 3/6  = 2  C1/C2. = -9/-18 = 2    For consistent pair of linear equation  A1/A2 = B1/B2 = C1/C2    Hence this pair of linear equation is consistent.       Hope it helps you.
