Answer:
-8,8
Step-by-step explanation:
since y=8 that add 8 to both sides to get rid of the -y. you would then get -4x=32. divide 32 by -4 and you would get -8 so the missing value would be -8
Answer:
and 
Step-by-step explanation:
Given

Required
Find x and y
In the second equation. Assume that:

Substitute
in the first equation


Collect like terms


Multiply through by 5


Solve for x

Substitute this value of x in 





It's an identity if it has infinite solutions and everything is right, which would mean that if both sides of the equation are equal after eliminating the variable then the variable does not matter and it will always be equal. If it is not equal after eliminating the variable then that means that no matter what the variable is, it does not matter and the equation will have no solution
Answer:
The answer is 6.
Step-by-step explanation:
Since w = 6 you would input the 6 where the w value is. Your equation should look like this: 2(6)-6
First you multiple the 2 x 6 which equals 12. After you minus 12-6 which equals 6. Therefore your answer is 6.
