The answer is a letter of the alphabet that falls between A and D!

sweetburger · Answer

So standard form is in the form

Ax+By=C

You can not have fractions.

Your first step is to move the x value to the left side. You do this by adding 3/4x to both sides.

Oh okay

sweetburger · Answer

Now your equation will look like this 
3/4x+y = 3

Now because we cant have fractions we must clear the denominator by multiplying everything by 4.
$$(4)\times \frac{ 3x }{ 4 } + (4)\times y= 3 \times( 4)$$

sweetburger · Answer

Now everything is in the proper form and you are left with 

$$3x + 4y = 12$$
