Answer:
768
Step-by-step explanation:
Answer:
y=3
x=-4
Step-by-step explanation:
-x+2y=10
*3
-3x+6y=30,
then add it with 3x+5y=3,
3x+5y=3
-3x+6y=30, would be...
0x+11y=33,
y=3,
x=-4
I think the answer is a I am learning this too
we are given the ordinary differential equation of dy/dx = 2y+1. The ODE is variable separable which means x and y can be grouped altogether explicitly. In this case, the equation becomesdy / 2y + 1 = dx
1/2 ln (2y + 1) = x + ln Cln (2y + 1) = 2x + ln C2y + 1 = C e 2x y = (C e 2x - 1)/2
The ODE y' + xy = x can be grouped into y' + x(y-1) = 0 'y' / y-1 = -xThis is variable separable
X = -8. This is the answer because two negatives multiplied together make a positive integer, and with x equaling -8, the equation would be completed. -8 • -X = 8. 8/2 - 3/2 = 5/2.
Your final answer: X = -8.
