Question

Solve the equation for X. Also there is 100 points attached to this

Answer 1

C

Explanation:

To sum matrices they have to be of the same proportions

and we sum the corresponding

so we have

`1)-3x_1+7=10\\\\-3x_1=3\\\\x_1=-1\\\\\\2)-3x_2+0=0\\\\-3x_2=0\\\\x_2=0\\\\\\3)-3x_3-1=8\\\\-3x_3=9\\\\x_3=-3\\\\\\4)-3x_4+2=-19\\\\-3x_4=-21\\\\x_4=7\\\\\\5)-3x_5-3=-18\\\\-3x_5=-15\\\\x_5=5\\\\\\6)-3x_6+4=10\\\\-3x_6=6\\\\x_6=-2`

so the answer is C

I cannot write a matrix but there you have the values

x_1 x_2 x_3

x_4 x_5 x_6
