4x-2y=12 -4x-9=54 How can you order a ladder?

Mathematics

Equations:

4x - 2y = 12
-4x - 9y = 54

Multiple them in both sides

4x - 2y - 4x - 9y = 12 + 54
-2y - 9y = 66
-11y = 66
y= -6

If y= -6 then put y in first or second equation.

I put it in first equation

4x - 2.(-6) = 12
4x + 12 = 12
x= 0

Therefore

(x,y) = (0, -6)

Y=4x+8x, Solve for x.<br><br> It's x=y/12, I just need to know how to work it out.
Scrat [10]

Step-by-step explanation:

<h2>Answer:-</h2>

\tt{y = 4x+8x}

First, we need to add up the x.

We know that 4+8 = 12, so

\tt{4x+8x=12x}

Now, equating it to y,

\tt{y = 12x}

Now, if I multiply \tt{\dfrac{1}{12}} on both sides,

I get,

\tt{\dfrac{y}{12}= \dfrac{\cancel{12}x}{\cancel{12}}}

Now, as 12 got cancelled , I got the final answer as

\boxed{\tt{x =\dfrac{y}{12}}}

Hope it helps :)
