Question

Calculate the values of p,q,r and s for each of the following if the two given matrices are the same matrix

​

Answer 1

see explanation

Explanation:

Given 2 equal matrices, then corresponding elements are equal , so

4 + p = 10 ( subtract 4 from both sides )

p = 6

5 + 2q = 6 ( subtract 5 from both sides )

2q = 1 ( divide both sides by 2 )

q = 0.5

7r = 7 ( divide both sides by 7 )

r = 1

4s = 16 ( divide both sides by 4 )

s = 4
