Equate the equations... just set 4x=2x+6 then solve for x

HI there.

Carrying on from heretohelp... 4x=2x + 6

Jonathan C.

24 February 2013

So take away 2x from both sides -> 2x=6 so x = 3 this is true as 4x would be 12 and 2x +6 = 12 as well: hope that helps. Jon

So when you do 4x=2x+6 then you take 2x to the left hand side to get 2x=6 and then divide by 2 to get x=3

you then put 3 back into one of the equations, and if you pick the first one you get y= 3 x 4, so therefore y =12, and if you put it into the second one you get y=2 x 3 + 6 and y =12 there as well

Differential Equations

Solve (D2-3D+2)y =x(x+4) and show that its general solution is given by y=Aex + Be2x +(x2/2) + (7x/2) + (19/4)

My work :

auxiliary eqn , m2 - 3m + 2= 0 m=1 , m=2

Reduced eqn : yn = Aex + Be2x

P.I. = 1/f(D)F(x) = (1/(D2-3D+2))(x(x+4))

P.I. = [(x2+4x) + ( (1/2)( 2- 3(2x) - 3(4) ) ) + (1/4)(92) )

P.I. = x2 + (4x/2) - (6x/4) - (5/2) + (18/4)

P.I. =(x2/2) + x + 8/4

General solution : y= Aex + Be2x + (x2/2) + x + 8/4

Could anyone point out my mistakes?

Simultaneous equations help

Hi, I need a bit of help on how to solve the following. y = -4x + 4 y = x2 -6x - 8 I have tried to substitute equation one into equation two ( RHS must be equal) to give -4x + 4 = x2 -6x -8 I have then added all like terms to give but im then stuck and I think i have got the method wrong. Bit confused due to x2 and y = as I thought i did understand how to solve these so im now annoyed. x2 -10x -4 Any help on how to solve this would be helpful. Thanks
