The standard form of a linear equation in general is given by:

Now we are given the equation :

In order to convert this into standard equation, we have to eliminate the 3 in the second term on the left side of equation.
Here 3 is in division ,so we have to perform opposite operation of division that is multiplication.
So multiplying both sides by 3 , we have

So that means option A.Multiply both sides of the equation by 3. The standard form of the equation is 12x – 2y = 24. is the correct advice given by Sofiya.
12
For every 1girl there are 2boys
1girl+2boys= 3/1girl
I think the answer would be be C.
<span>.99(15) = 1.35x
14.85 = 1.35x
14.85/1.35 = 11
I think it is 15. I am not sure about the proper way to solve this....I just know that if he sold 15 brownies, he could buy 11 packs with exactly no change left over.</span>
