4x+y=26 replace y with (x-4) & solve for x in this equation.
4x+(x-4)=26
4x+x=26+4
5x=30
x=30/5 <span>
x=6 answer.
y=6-4
y=2 answer.
Proof.
4*6+2=26
24=2=26
</span>26=26 <span>Y=x-4

X = # 0.75 stamps y = # 0.45 stamps total postage = $5.70
Answer:
Quadrant II
Step-by-step explanation:
(-5,6)
The x coordinate is negative so the quadrant is either 2 or 3
The y coordinate is positive so the quadrant is either 1 or 2
To make both happen, it must be in quadrant 2
Quadrant II
It will never be the same, it is impossible.
