Answer:
<em>(4, 1) </em>
Step-by-step explanation:
Method elimination would be good for this system
2x - y = 7 ........ <em>(1)</em>
x + y = 5 ......... <em>(2)</em>
<em>(1)</em> + <em>(2)</em>
3x = 12 ⇒ x = 4
4 + y = 5 ⇒ y = 1
<em>(4, 1)</em>

Answer:
375000
Step-by-step explanation:
We have that in this case the following proportion would be fulfilled:
Price * Distance / area
Now, we have that for a distance of 45 km and an area of 900 m ^ 2 the price is 250,000, now for a distance of 40 km but with an area of 1,200 m ^ 2, how would the price be, we replace:
250000 * 45/900 = P * 40/1200
12500 * 1200/40 = P
P = 375000
Which means that for these conditions the price is 375000.
