Solve system of equation using elimination

Mathematics

First let's get rid of the x by multiplying the tip equation by -2

-2 (-6x - 2y = -4)
+
(-12x - 5y = -13)

Distribute

(12x + 4y = 8)
+
(-12x - 5y = -13)

x cancels out and you're left with

-1y = -5
y = 5

Now solving for x, plug in your y into one of the equations

-6x - 2(5) = -4
-6x - 10 = -4
-6x = 6
x = -1

(-1 , 5) is the solution

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.
