Assignment: \bold{Solve \ Equation: \ 8x - 3y = 12}

<><><><><><><>

Answer: \bold{y=4}

<><><><><><><>

Explanation: \downarrow\downarrow\downarrow

<><><><><><><>

[ Step One ] Replace 3 For X

\bold{8\cdot \:3-3y=12}

[ Step Two ] Multiply Numbers: \bold{8\cdot \:3=24}

\bold{24-3y=12}

[ Step Three ] Subtract 24 From Both Sides

\bold{24-3y-24=12-24}

[ Step Four ] Simplify

\bold{-3y=-12}

[ Step Five ] Divide Both Sides By -3

\bold{\frac{-3y}{-3}=\frac{-12}{-3}}

[ Step Six ] Simplify

\bold{y=4}

Answer:

y = 4

Step-by-step explanation:

Plug 3 in for 'x' in the equation and solve for 'y'...

8(3) - 3(y) = 12

   24 - 3y = 12

       -3y = -12

             y = 4

What 2 numbers multiply to -147 but add to -14?
Bezzdna [24]
Okay, so let's go over multiplying negative numbers.  A positive times a positive is a positive, right?  But a negative times a negative is also a positive.  Only a negative times a positive (or a positive times a negative) gives you a negative number.  So, we know that one of our 2 numbers in this question must be negative; the other must be positive.

Let's now take a look at the factors of -147, starting with the positives.  Obviously, -147 and 1 are factors: -147 * 1 = -147.  What other factors of -147 are there?

What about 7?  Try it: -147 / 7 = -21.  So here are two factors: -21, and 7.  They multiply to -147.  Do they add up to -14?  Let's see: -21+7 = 7+(-21) = 7-21= -14.  Yup, that works!

Answer: -21 and 7

5. Find the general solution to y'''-y''+4y'-4y = 0
CaHeK987 [17]

For any equation,

a_ny^(n)+\dots+a_1y'+a_0y=0

assume solution of a form, e^{yt}

Which leads to,

(e^{yt})'''-(e^{yt})''+4(e^{yt})'-4e^{yt}=0

Simplify to,

e^{yt}(y^3-y^2+4y-4)=0

Then find solutions,

\underline{y_1=1}, \underline{y_2=2i}, \underline{y_3=-2i}

For non repeated real root y, we have a form of,

y_1=c_1e^t

Following up,

For two non repeated complex roots y_2\neq y_3 where,

y_2=a+bi

and,

y_3=a-bi

the general solution has a form of,

y=e^{at}(c_2\cos(bt)+c_3\sin(bt))

Or in this case,

y=e^0(c_2\cos(2t)+c_3\sin(2t))

Now we just refine and get,

\boxed{y=c_1e^t+c_2\cos(2t)+c_3\sin(2t)}

Hope this helps.
