X-5y=17 then x = 5y + 17
replace x = 5y + 17  into <span>-4x+y=8

</span>-4(5y + 17) +y = 8
-20y - 68 + y = 8
-19y = 8 + 68
-19y = 76
y = 76/-19
y = -4

x = 5y + 17
x = 5(-4) + 17
x = -20 + 17
x = 3

Answer: the order pair (3, -4)

Suppose a 5x8 coefficient matrix for a system has pivot columns. Is the system​ consistent? Why and Why not?
Lyrx [107]

Step-by-step explanation:

All the 5 rows of the coefficient matrix (since it is of order 5×8) will have a pivot position. The augmented matrix obtained by adding a last column of constant terms to the 8 columns of the coefficient matrix will have nine columns and will not have a row of the form [0 0 0 0 0 0 0 0 1]. So the system is consistent.
