Hello!  Is this solving a system of 3 equations simultaneously?

imstuck · Answer

I'm not sure exactly what it is you are asking for in your post.

anonymous · Answer

Solve y equals two times x plus three for x.

 x equals y divided by negative two minus three

 x equals y plus three divided by two

 x equals y minus three divided by negative two

 x equals y divided by three plus two

y=2x+3.  And you need to solve that for x.  Ok, the first thing you need to do is move the 3 to the other side of the equals sign.  If the 3 is added to the one side, do you know how to move from that side to the other side?  What mathematical operation would you use?

volume

you are not dealing with volume in this problem

oooo sorry im not good with math

imstuck · Answer

Did you maybe mix up two problems?

anonymous · Answer

its tell me that y=-2x +3

imstuck · Answer

The problem you are solving for x is y = 2x + 3.  You have to get the x all by itself, with nothing 'attached' to it and nothing on the same side of the = sign.  So that means you have to move the 3 to the other side.  It's added to the 2x, so in order to move it you have to subtract it, like this:
y-3=2x+3-3--> y-3=2x is what you have now.

texaschic101 · Answer

I think the problem is actually y = -2x + 3

imstuck · Answer

y-3 = 2x.  Now you have to move the 2 away from the x.  The 2 is multiplied by the x, so in order to "undo" the multiplication, you have to divide.  Divide both sides by 2 like this:$$\frac{ y-3 }{ 2 }=\frac{ 2x }{ 2 }$$

imstuck · Answer

The 2's on the right side will cancel each other out, leaving you only with an x.  So your answer to this is:$$\frac{ y-3 }{ -2 }=x$$  The third choice down.
