# Math Help - Rewrite equations and formulas

1. ## Rewrite equations and formulas

can you explain how to do this?
ax+b=c solve for X

theses are the steps:
ax+b=c
ax=c-b [[how do you get from here]]
X=c-b/a [[to here, how does the a and x do that?]]

x=c-b/a (thats a fraction)

thats an example in
my text book but i dont understand how you get that answer
thankk youu(:

2. It should be

$
x = (c - b) / a
$

If the book says $x = c - (b/a)$ then it is wrong. Typo?

If you're not familiar with how to solve linear equations, you'll need to study that first, because you use those techniques for solving literal equations such as the one you've posted.

To learn how to solve literal equations, try here.

Once you've learned the basic terms and techniques, please attempt the exercise. The subtraction to move $b$ to the other side of the "equals" sign is the first step. Then you divide through by the $a$ to complete the solution.
