2x-2y-z=3
4x + 5y - 2z = -3
3x + 4y -3z= -7. solve using determinant method

Step-by-step explanation:

4x-4y -2z = 6  ( first equation x2)

4x+ 5y-2z =-3   ( If you substract these two)

-9y= 9   so y= -1

2x-z =1  (multiple by 3 ) then 6x-3z=3

3x-3z= -3  

3x=6 x=2  and z=3

The answer is x=2, y=-1 and z= 3

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6
