Find a and b if

KnowledgeBoat · Accepted Answer

Given, By definition of equality of matrices we get, ⇒ 2a - 4 = 0 or 2a = 4 or a = 2 ⇒ 2b - 8 = -2 or 2b = -2 + 8 = 6 or b = 3 ⇒ 2a - 2b = -2 (Eq 1) Checking whether a = 2 and b = 3 satisfies Eq 1, ⇒ 2a - 2b = -2 L.H.S. = 2a - 2b = 2(2) - 2(3) = 4 - 6 = -2 = R.H.S. ∴ a = 2 and b = 3. Hence, the values are a = 2 and b = 3.
