Make sure that you work one step at a time, applying the basic rules of algebra at every step. Mark's solution below is an exemplary solution, there are other ways you could do it which would get the same solution.

Hi there,So this problem requires you to find the value of x. To do this, first add the 9 to the -23. You should get:2 (3x + 8) = -14Then, multiply out the bracket - so times everything within the bracket by the 2 on the outside. This will leave you with;6x + 16 = -14Now you should take 16 away from both sides of the equation in order to keep it balanced. Hence you will have:6x = -30The final step is to divide both sides of the equation by 6, leaving you with:x = -5

2(3x+8) = 23+9or 6x+16=32or 6x=16or x = 16/6=2.67

2(3x+8) = -23+9goes to:6x + 16 = -23+9 (because you multiply 2 and 3x together to get 6x, and 2 and 8 together to get 16)This goes to:6x + 16 = -14 (-23 + 9 is the same as 9 - 23, which equals -14)This goes to:6x = -30 (you minus 16 from both sides - you're allowed to do this because it's the same to both sides)This goes to:x = -5 (because you divde both sides by 6)Ta Da! Hope this helps.

Step 1: Simplify both sides of the equation -23 + 9 = -14 2 (3x + 8) = 6x + 16 Therefore 6x + 16 = -14Step 2: Collect all the terms of "x" on one side, and all of the numbers on the other. In this case this is done by subtracting 16 from both sides (6x + 16) - 16 = -14 - 16 --> 6x = -30Step 3: Further simplify to find the value of x. In this case by dividing both side of the equation by 6 6x/6 = -30/6 --> x = -5

6x + 16 = -146x = -14 -166x = -30x = -30/6 = -5

6x + 16 = -146x = -14 -166x = -30x = -30/6 = -5

Expand the brackets and then it becomes a lot easier

when u multiply 2 in brackets then u obtain 6x+16=-146x=-14-16 6x=-30divide 6 on both sidesx=-5

Step 1. Divide both sides of the equation by 2:2/2(3x+8)=(-23+9)/2=> 3x+8=-14/2=> 3x+8=-7Step 2. Substract 8 from both sides3x+8-8=-7-8=>3x=-15Step 3. Divide both sides by 33x/3=-15/3=> x=-5

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?
