treat x+y as a variable u.
dy/dx=u
dy=udx
u=x+y
du/dx=1+dy/dx
du/dx=1+x+y
du/dx=1+u
du/(1+u)=dx
dy=[u/(1+u)]du
y+C=u-ln(u+1)
y+C=x+y=ln(x+y+1)
-x+C=ln(x+y+1)
Ce-x=x+y+1
Ce-x-x-1=y
-2y square exp power -2x-1
This question has already been answered in detail and the value of x is 11/15 which when substituted into the equation results in: 12/11 = 12/11
-1
Move 3 over the right side of the equation so the equation would be x = -3. The graph of this would be a verticle line at x= -3
x/5 = 8/21 x = 8/21 * 5 x = 1.904761905
-2y square exp power -2x-1
x equals 4 over 35
(4/9) x = That's not an equation. If there were a number after the 'equals' sign, then we could calculate the value of 'x'. But as it is, there's no question there, so there's nothing to solve.
b = 14
This is an inequality equation in the form of: ii < xxii/viii which is the same as 2 < 22/8
The possibility of your next question being noob is approximately 29 over 16.
h/(-3 - 7) = 10h/-10 = 10h = -100
h/9=7 multiply both sides by 9 h=63
You cannot solve this single equation. You can either change the subject so that it gives x = 12/y or xy = 12, which is the equation of a rectangular hyperbola.
In order to solve for X, or find out what X equals, you need to get the X alone on one side of the equation. In this case, first you subtract the Y so that the equation becomes 5x=10-y. Then you divide both sides by 5. Now the equation is X=(10-y)/5 (or X equals the quantity of 10-y over 5).
Density equals mass over volume. Set up the equation and solve for volume.
cross multiply to solve: 100 x 4200 = 87 Y solve for Y by doing 420,000 divided by 87, which equals 4828 (rounded off)
