4x + 3y + z= -6
x-3y + 2z=0
11x-2y + 3z = - 26
Answer:
y= - 271/71
x=755/71
z =4866/71
Step-by-step explanation:
For resolve a system you multiply an equation of the system or add two of the equation and replace the result in the system
Add the 1st and 2nd, and replace the 2nd
4x + 3y + z= -6 4x + 3y + z= -6 4x + 3y + z= -6
(-4) (x-3y + 2z=0) → -4x +12y -8z =0 → +15y -7z = -6
11x-2y + 3z = - 26 11x-2y + 3z = - 26 11x-2y + 3z = - 26
Add the 2nd and 1st, and replace the 1st
4x + 3y + z= -6 4x + 3y + z= -6 4x + z= -6
(-1/5)( 15y -7z = -6) → -3y -7/5z =6/5 → -3y -7/5z =6/5
11x-2y + 3z = - 26 11x-2y + 3z = - 26 11x-2y + 3z = - 26
Add the1st and 3rd, and replace the 3erd
(-3)( 4x + z= -6) -12x - 3z= 18 -12x - 3z= 18
-3y -7/5z =6/5 → -3y -7/5z =6/5 → -3y -7/5z =6/5
11x-2y + 3z = - 26 11x-2y + 3z = - 26 -x-2y = - 8
Add the1st and 3rd, and replace the 1st
(1/3)(-12x - 3z= 18 ) -4x - z= 6 -4x - z= 6
(5)(-3y -7/5z =6/5) → -15y - 7z = 6 → -15y - 7z = 6
-x-2y = - 8 (-4)(-x-2y = - 8) 4x + 8y= 32
Add the 1st and 2nd, and replace the 2nd
(-7)(8y - z =38) -56y +7z= 266 -56y +7z= 266
-15y - 7z = 6 → -15y - 7z = 6 → -71y=271 → y= - 271/71
(1/4)(4x + 8y= 12) x+2y=3 x+2y=3
-56y +7z= 266 → -8y + z =38 → z =4866/71
x+2y=3 → x=755/71
When you look at the graph, the X is the x value and the one on the f(x) is the y value, imagian it is on a graph and x is the steps you have to walk then imagain a ladder you have to go as high as the f(x) value says, then mark them. if they follow a pattern then write it down, if it does not then write incosentant.
Have a nice day.
