System of solutions with matrices: [1 3 5]
[0 1 1/2]
What is the x-coordinate of the solution to the system?
a.) 7/2
b.) 13/2
c.) 5
d.) 3

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
