Last question! Please show work. Really need to get this done in 1 hour

Step-by-step explanation:

explanation is in the attachment

hope it is helpful to you

x = 1, y = 2 , z = 3

Step-by-step explanation:

Now add ( 1 ) and  (4)

y = 2

Now multiply ( 1 ) by  2 and (3) by 3

------ ( 5 )

Substitute y = 2 in ( 5 ) :

z = 3

Substitute z = 3 and y = 2 in ( 1 ) :

x = 1

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
