Answer: 3,220
Step-by-step explanation: What you do first is find the volume of the room which is 1,610. So after that you multiply 1,610 by 2 since Maria wants "two" coats of paint on each wall.
Answer:
Since, the given solution is (2, 14). Therefore, 7x−y=0. Similarly, another equation can be−x+y=−2+14=12. Similarly, another equation can be−2x−y=−2(2)−14=18.
X cannot be 0 because if it is, it would be undefined
we are given

we can see that
each terms are multiple of 2
so, we can factor out 2

we can divide both sides by 2

we can rearrange it

now, we can move 10 on right side


now, we can add both sides 7^2 and 5^2


we can simplify it

we can also write as
