Solve the following system of equations using gaussian elimination

6x+2y-4z=15

-3x+4y+2z=-6

4x-6y+3z=8

i am having trouble solving these and i really need because i don't understand how to do problems like this. you so much

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;
