Solve by using any method of substitution<br><br>4 +8x = y <br>6x - y = 2
Bumek [7]

Answer:

(-3,-20)

Step-by-step explanation:

4 +8x = y ...... equation (1)

6x - y = 2 ........equation(2)

from equation 2

6x - y = 2

6x -(4+8x) =2

6x - 4 + 8x = 2

    +4              +4

6x - 8x = 6

-2x=6

divide by -2

x= -3

put x in equation (1) to solve for y

4 + 8x = y

4+8(-3)=y

4-24=y

-20=y

y= -20

solution = (-3,-20)

Can anyone help me please? it’s urgent.

It said "no association between this dude winning and loss in harsh condition"

now look at harsh condition, total is 20, since there is no association that means they are the same, which is 10 and 10

WIN column total is 168, 158 for normal condition, 10 for harsh condition, adds up to 168.

LOSS column total is 72, 62 for normal condition and 10 for harsh condition, adds up to 72.

if u wana check if it adds up with Normal Condition, 62 plus 158 is 220.

checked, complete, this is david signing off
