We have that
<span>x - y = 4-------> multiply by -1-----> -x+y=-4-----> equation 1
x+ 2y = 4------> equation 2
add equation 1 and equation 2
-x+y=-4
x+2y=4
-----------------
0+3y=0-----> y=0
x+2y=4------> x+0=4------>x=4
the solution is the point (4,0)</span>
The answer is the last one -4 < x < 1/2
The answer is no solution
There is no way I can answer this without the graph
Answer:
4
Step-by-step explanation:
4×4=16 (4 squared)
16-4=12 (4 is 12 less than its suare =16)
