Answer:
x-4y=16; x
Step-by-step explanation:
as coefficient of X is one whereas in second equation it is 3 for X and 4 for y ..
Step-by-step explanation: The number in front of your variable is called your coefficient and notice that the x does not have a coefficient.
When that happens, when there is no number in front
of your variable, you can put a 1 there to fill that position.
So x can be thought of as 1x.
