This isn't too bad. When a question asks for a negative plus a negative, just think of it as the negative minus a negative. -3-17. When you subtract two negatives, it's kinda like asking for adding two positives. The answer will be 20, not 14 as lots of folks mistake this part.
Now that we know -3-17, we have to add 13. This is adding a positive to a negative, so it's subtraction. -20+13. Same as asking 13-20. Which is -7.
Final answer: -7

Answer:
(2,5)
or x=2, y=5
Step-by-step explanation:
3x+2y=16
substitute y =x+3 every place you see a y
3x + 2(x+3) = 16
distribute
3x + 2x +6 = 16
combine like terms
5x+6 = 16
subtract 6 from each side
5x+6 -6 =16-6
5x =10
divide by 5
5x/5 = 10/5
x = 2
now we need to find y
y = x+3
y = 2+3
y=5
(2,5)
or x=2, y=5
The answer is 9. Solve the 4•3 first which is 12. Then, do as per normal. 12+12-15= 9.
