Find the values of x and y if .

Question

KnowledgeBoat · Accepted Answer

Given . By definition of equality of matrices, we get 2x + y = 5 [....Eq 1] 3x - 2y = 4 [....Eq 2] 2x + y = 5 ⇒ y = 5 - 2x Putting value of y in Eq 2, 3x - 2(5 - 2x) = 4 ⇒ 3x - 10 + 4x = 4 ⇒ 7x = 14 ⇒ x = 2. ∴ x = 2, y = 5 - 2x = 5 - 4 = 1. Hence, the value of x = 2 and y = 1.
