<p>If a + 2(x+1) = S, what is x+1 in terms of s and a?</p>
<p>How do you solve this?</p>
<p>Lol
just shift a to the right hand side and divide by 2 throughout
x+1 = (S - a)/2</p>
<p>Maybe you should review some algebra before the next SAT</p>
<p>idk if this was luck, but i just assigned numbers to A and X and then got the answer</p>
<p>do you have the first blue book for the new SAT?</p>
<p>when the question says somethign to the lines of what is blank in terms of blank, you know the first blank must be isolated on one side of the equal sign and the other side of the sign is your answer. what is x+1 in terms of s and a? Do what u have to do to make x+1 alone and youll get your answer</p>
<p>"If a + 2(x+1) = S, what is x+1 in terms of s and a?"</p>
<p>So what you're trying to do is isolate (x+1) to find it's equivalent in terms of S and a.</p>
<p>a + 2(x+1) = S</p>
<p>Frist, subtract a from both sides.</p>
<p>2(x+1) = S - a</p>
<p>We almost have x-1 by itself. Now divide both sides of the equation by 2.</p>
<p>x+1 = (S-a)/2</p>
<p>And that's your answer. Making sense?</p>
<p>algebra, just isolate x+1</p>
