Answer: Choice D) ordered pair is not a solution to the second equation
We can see this by replacing x and y with 1 and -4 respectively
2x + y = 4
2*1 + y = 4 .... replace x with 1
2*1 + (-4) = 4 ... replace y with -4
2 - 4 = 4
-2 = 4 .... this equation is false because -2 and 4 are different values
The last equation being false means that the original equation 2x+y = 4 is also false when (x,y) = (1,-4). Therefore, this ordered pair is not a solution to the second equation 2x+y = 4
A solution to the system must make BOTH equations true simultaneously, not just one.
Answer:
D
Step-by-step explanation:
2x + y = 4
If you substitute x = 1, and y = -4, then
2(1) - 4 = 2 - 4 = -2 not 4
Answer:
47
Step-by-step explanation:
In the first step, inside the brackets I took the LCM and then in second step I subtracted 3 from 11 which gave result of8÷8=1 then 1 is multiplied to 2 which becomes 49-2 and 47 is the result
