Question #6324

Solve (matrix)
[-6, 3t+9]
[-1, 4]
=
[-6, 6t-4]
[-1, 3y+2]
for each variable.

Expert's answer

Two matrices are equal if and only if their elements are equal. So, we get the

system of 2 equations:

3t+9 = 6t-4

4 = 3y+2.

From the first equation we

have 3t = 13, t = 13/3; from the second 3y = 2, y = 2/3.

The solution: t =

13/3, y = 2/3.
