Answer :
14-4x=2y divide 2 to both sides
VVVVV
7-2x=y you will need this on the next step
-----------------------------------------------------
y+2x=7
y=7-2x
(7-2x)+2x=7 -------> 7-2x+2x=7
7=7
The answer is C.

-----------------------------------------------------
y+2x=7
y=7-2x
(7-2x)+2x=7 -------> 7-2x+2x=7
7=7
The answer is C.
Since the value on both sides are the same, hence there are infinite number of solution for the system of equation
System of equations
Given the system of equations expressed as:
Y+2x=7
14-4x=2y
Using the substitution method.
From equation 1, y = 7 - 2x
Substitute into equation 2
14-4x = 2(7 - 2x)
Expand
14 - 4x = 14 - 4x
0x = 0
Since the value on both sides are the same, hence there are infinite number of solution for the system of equation
