For the 1st problem, solve the 2nd equation for x.
x = -1 - y
Now, replace x in the 1st equation with (-1 - y)
2(-1 - y) - 3y = 2
-2 - 2y - 3y = 2
-2 - 5y = 2
-5y = 4
y = -4/5
x = -1 - (-4/5) = -1 + (4/5) = -1/5
The solution is (-1/5, -4/5)
For the 2nd problem, multiply the top equation by 15 and the bottom equation by -12. That gives us:
10x - 12y = 15
-36x +12y = 84
Add the two together, which gives us:
-26x = 99
x = -99/26
Now, put this value of x into either equation to solve for y
3(-99/26) - y = -7
-297/26 - y = -7
-y = -7 + 297/26
-y = 115/26
y = -115/26
The solution to this system is (-99/26, -115/26)
4.3 I believe. That's the answer I got.

Sorry. :(((
Hope this helped, tho. :))
Answer:
Step-by-step explanation:
Things to remember:
1). When we divide a number having decimal by 10, 100, 1000 or any number multiple of ten, decimal point of the numerator shifts left by the number of zeros present in denominator.
Example: 
2). When we multiply a decimal number by 10, 100, or any number number multiple of 10, decimal point of the original number shifts right by number of zeros present in multiplier.
Example: 2.0 × 100 = 200
In this question, 0.014 × 100000 = 1400.000
Therefore, product of 0.014 and 100000 is 1400 because the decimal point in 0.014 moves 5 places to the right.
Answer:
B. There will be a little overlap.
