It should be
If the book says then it is wrong. Typo?
can you explain how to do this?
ax+b=c solve for X
theses are the steps:
ax=c-b [[how do you get from here]]
X=c-b/a [[to here, how does the a and x do that?]]
The answer is:
x=c-b/a (thats a fraction)
thats an example in
my text book but i dont understand how you get that answer
can somebody please help?
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 to the other side of the "equals" sign is the first step. Then you divide through by the to complete the solution.
