How does this work for solving equations and formulas: ax-b= c for x I'm having problems with my algebra 1 work. I just don't understand it.

To solve a problem like ax-b=c for x, we normally have to go through the following steps.

Here a, b and c are numbers and x is an unknown oa variable.

ax-b=c is the equation to solve.

Add b to both sides.

ax-b+b=c+b.

Simplify:

ax=c+b.

Divide by a both sidesby a:

ax/a= (c+b)/a

x=(c+b)/a or

x=(b+c)/a is the solution.

Example : Solve 10x- 20 = 30.

Follow the above steps:

Add 20 to both sides.

10x-20+20 =30+20

Simplify:

10x=30+20 or

10x=50

Divide both sides by 10 :

10x/10=50/10.

Simplify:

x=5. So x=5 is the solution of 10x-20=30 by following the above steps.
