(1 point) linear system - three variables solve the following system of equations using gaussian elimination method. if there are no solutions, type "n" for both x, y and z. if there are infinitely many solutions, type "z" for z, and expressions in terms of z for x and y. 6x + 8y + 72 = -3 - 3x + 6y + 6z = 5 2x – 9y – 32 = 7

≈ -5.1857

≈ -5.4857

≈ 3.7262

Step-by-step explanation:

Rewrite the equation system as:

Now, write the system in its augmented matrix form:

applying row reduction process to  its associated augmented matrix:

Swap R1 and R3, and then Swap R1 and R2:

R3+2R1

3R2+2R1

15R3+20R2

Now we have a simplified system:

From (3):

(4)

Replacing (4) in (2)

(5)

Finally replacing (5) and (4) in (1)

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
