z-3.6=46.8 add 3.6 to both sides z=50.4
Z tranform can be used to solve the differential equations occurring in electrical problems.

(1/x) - (1/y) = (1/z) Get the left-hand side over a common denominator:- (y-x)/xy = 1/z Take the reciprocal of both sides:- z = xy / (y-x)
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)
20y2 - 11yz - 3z2 = 20y2 + 4yz - 15yz - 3z2 = 4y(5y + z) - 3z(5y + z) = (4y - 3z)(5y + z)
27y3 + 125z3 = (3y + 5z)*(9y2 - 15yz + 25z2).
What are we solving here for, Z, X, or Y?If solve for Z then the answer would be z = x + yIf solve for X then the answer would be z = z - yIf solve for Y than the answer would y = z - xHope this help.
Set up the equation and solve for z: 28 + z = 56 (next, subtract 28 from each side of the equaition to solve) z = 28
6+z = 3 z = 3-6 z = -3

The expression has no solution but it can be simplified to: z+6
z-3.6=46.8 add 3.6 to both sides z=50.4
z=.3
You should write the question out as z= (y/x). To solve this, you would multiple x to the other side to get y alone. Then you would multiply z to the other side. z= (y/x) Given xz= y x= y/z
In simple cases such as these, you can solve inequalities just like an equation. In this case, you add 3 to both sides.
