Question

A system of equations has 1 solution. If 4x – y = 5 is one of the equations, which could be the other equation?

Answer 1

4x =5+y ------ 1

X =5+y/4 ------ 2

hope this is useful

Answer 2

Answer:

another equation must be  in the form ax +by =c   where a/b is not -4

Step-by-step explanation:

4x -y =5

ax +by =c  must be intersecting lines

they are not parallel

slpoe are not equal

slopes -a/b and -4/-1=4 not equal

a/b is not -4
