What is the solution to this system of equations?
a = 1, b = –1, c = 2
a = 1.5, b = –1, c = 2
a = 2.5, b = –3, c = 2
a = 3, b = –3, c = 2

Answer 1

I can’t see the image you attached. Please either paste the matrix entries (rows) here or re-upload the image. For example, type it as an augmented matrix like:

[ a11 a12 a13 | b1 ]
[ a21 a22 a23 | b2 ]
[ a31 a32 a33 | b3 ]

Once you post the entries I’ll solve and pick which of the four answer choices is correct (or show elimination step-by-step).
