2x-y=7
y=2x+3
Substitute (2x+3) in for y in the first equation
2x-(2x+3)=7
2x-2x-3=7
-3=7
Becuase -3 does not equal 7 the answer is no solution

Answer:
Step-by-step explanation:
its 6
Answer:
w = -6
Step-by-step explanation:
Adding 4 to both sides (we do this to get rid of the -4) gives us:
-4 + w + 4 = -10 + 4
w = -6
The function has two imaginary and two real zeros.
