Answer :

Given two matrices are equal. We know that if two matrices are equal then the elements of each matrices are also equal.

x + 3 = 0

x = 0 – 3 = – 3 …… (1)

And z + 4 = 6

z = 6 – 4 = 2 …… (2)

And 2y – 7 = 3y – 2

2y – 3y = – 2 + 7

– y = 5

y = – 5 …… (3)

4x + 6 = 2x …… (4)

a – 1 = – 3

a = – 3 + 1 = – 2 …… (5)

2c + 2 = 0

2c = – 2

c = – 1 …… (6)

b – 3 = 2b + 4

b – 2b = 4 + 3

– b = 7

b = – 7 …… (7)

x = – 3, y = – 5, z = 2 and a = – 2, b = – 7, c = – 1
