Answer:
30 grade
Is the answer according
to me
15
Step-by-step explanation:
3x3=9
so therefore you need to multiply 2 by 3=6
9+6=15
second one because
only x+2y=8 passes through the point (2,3)
the proof is 2+2*3=2+6=8
if we replace the given point to the other equations we will take wrong results for example
first equation
x+2y=4. 2+2*3=2+6=8 that is not equal to 4
