WebJan 16, 2024 · As the given matrices are equal, so A = B. We can see that the order of the given matrices is equal, so the equality of matrices holds if and only if the corresponding elements are also equal. So, 2a + 3b = 5 ⇢ (1) a + b = 1 ⇢ (2) a = 1 − b ⇢ (3) Now, substitute the value of a = 1 − b in equation (1) ⇒ 2 (1 − b) + 3b = 5.
