Answer:
5
Step-by-step explanation:
Answer:
None of the above.
Step-by-step explanation:
The system of equations which should have the same solution as the system below;
x + 4y = 11
4x + 2y = 16
is
x + 4y = 11
-8x - 4y = - 32
This system of equations is missing from your choices.
The trick is that -2 is multiplied to the second equation of the first system.
i.e -2 (4x + 2y = 16) gives; -8x - 4y = -32
1) Open up any parentheses if there are any
2) Combine like terms (moving the variable to one side and other numbers to the other)
3) solve using pemdas/bedmas and any additional steps you need to isolate the variable
4) if x turns out negative, invert the sign
Example:
2x+5=3(x+1)
Open up the parentheses by multiplying it by 3
2x+5=3x+3
Combine like terms
2x-3x=3-5
-x=-2
x=2
I hope this helps!
