Question 763258: Find the values of the variables of the matrix.
2+t 0 = -5 0
8 2 8 1y-2
A. t = –7, y = 0

B. t = –7, y = 4

C. t = 4, y = –7

D. t = –3, y = 4

equate the corresponding parts to get

2+t = -5

t = -5 - 2

t = -7

----------------------

2 = 1y - 2

2 + 2 = 1y

4 = 1y

1y = 4

y = 4/1

y = 4

So the answer is choice B. t = –7, y = 4
