Answer 2

Answer:

This is it :

Step-by-step explanation:

LET

X  +  Y  = 8

+       +

Z   -   A  = 6

=         =

13        8

So, we have

X+Z=13

X+Y=8

Subtract,

Z-Y=5                                ------1)

Also,Y+A=8

        Z-A=6

Add,

Z+Y=14                              ------2)

Add 1) and 2),

2Z=19

Z=9.5

From 1),

9.5-Y=5

Y=9.5-5=4.5

Put it in Diagram,

X+Y=8

X=8-4.5=3.5

AGAIN,Y+A=8

A=8-4.5

A=3.5
