KnowledgeBoat · Accepted Answer

(i) Since, The order of the matrix is 2 × 1. (ii) Let Given, By definition of equality of matrices we get, 2x + y = 7 or y = 7 - 2x (...Eq 1) -3x + 4y = 6 (...Eq 2) Putting value of y from Eq 1 in Eq 2 ⇒ -3x + 4y = 6 ⇒ -3x + 4(7 - 2x) = 6 ⇒ -3x + 28 - 8x = 6 ⇒ -11x = 6 - 28 ⇒ -11x = -22 ⇒ x = 2. ∴ x = 2 and y = 7 - 2x = 7 - 2(2) = 7 - 4 = 3. Since, Hence, the matrix
