Question

5. Solve the following system of equations: 3x – 2y + z = –4 x + y – z = –2 2x + 3y = 4

Answer 1

Answer:

x=-1;y=2;z=3

Step-by-step explanation:

solving ;3x-2y+z=-4 ; x+y-z =-2

we get 4x-y=-6

solving 4x-y=-6 and 2x+ 3y =4

we get y= 2

substitute y in 2x+3y =4

we get x=-1

if we substitute x,y in x+y-z =-2

we get z= 3
