Use elimination
Multiply first equation by 4
12a - 8b = 56
12a + 9b = 39
Subtract both
-17b = 17
b = -1
Plug in -1 for b
3a - 2(-1) = 14
3a = 12, a = 4
Final answer: a = 4, b = -1

Answer: 2584
Step-by-step explanation:
We can find N with 2584 and 4181.
4181 - 2584
= 1597
We can also check our answer by adding 1597 and 987
1597 + 987
= 2584
Since the legs of the triangle are 1 and 1 the hypotenuse would be 1 also. And since squares have equal sides you know that every other side of the square are 1. The algorithm for area is base times height. So 1 times 1 is 1 unit squared.<span />
