Question

I need help with this !!!!!

Answer 1

Answer:

top left=4, top right =9, bottom left=12, bottom right =8 -- set it up as a system of small equations.  

Step-by-step explanation:

x+y=13

x+w=16

y+z=17

w-z=4

x=16-w

y=17-z

then substitute.

(16-w)+y=13

-w+y= -3

-w+(17-z)= -3

-w-z = -20 add that to w-z=4

-2z= -16

z=8

then plug back in until you have all 4 values

w-(8)=4 --> w=12

-(12)+y= -3 --> -12+y= -3 --> y=9

x+(9)=13 --> x=4

Answer 2

Answer:

4 + 9 = 13

+ +

12 - 8 = 4

= =

16 17

Took a while to solve but hope this helps!!
