Solve the system of equations by finding the reduced row-echelon form of the augmented matrix for the system of equations. 2x+y+42-16
5x - 2y + 22-1
x + 2y-32=-9

a. (-1, 2, 22)
b. (-10, 22, 42)
c. (-1, 2, 4)
d. (-10, 2, 22)

Which statements about the system are true? check all that apply. y =1/3 x – 4 3y – x = –7 the system has one solution. the system consists of parallel lines. both lines have the same slope. both lines have the same y–intercept. the equations represent the same line. the lines intersect.
