You need to clarify what you want to solve for. If you're solving for z, then we can say:
dz/dt + 4et + z = 0
∴ dz/dt = -4et - z
∴ ∫(dz/dt) dt = -2et2 - zt + C
∴ z = -2et2 - zt + C
∴ z + zt = -2et2 + C
∴ z(1 + t) = -2et2 + C
∴ z = (-2et2 + C) / (1 + t)

Solve the equation four over nine times x equals?
(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.

h/(-3 - 7) = 10h/-10 = 10h = -100
How do you solve for x in 5x plus y equals 10?
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).
What is the answer to this equation 100 over 87 is equal to Y over 4200?
cross multiply to solve: 100 x 4200 = 87 Y solve for Y by doing 420,000 divided by 87, which equals 4828 (rounded off)
What is the answer to y equals twelve over x?
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.
