# Solve for A, B and C If (-4, a + 5),(3, 2) = (B + 4, 2),(2, X- 1) - Mathematics

Sum

Solve for a, b and c if [(-4, a + 5),(3, 2)] = [(b + 4, 2),(3, c- 1)]

#### Solution

If two matrices are equal, then their corresponding elements are also equal.

a + 5 = 2 ⇒ a = -3

-4 = b + 4 ⇒ b = -8

2 = c – 1 ⇒ c = 3

Is there an error in this question or solution?
