Solving 2-step linear equations

Solving 2-step linear equations are the most simplest algebraic equations to solve:)

They are simply finding out what the letter is:)
Unfortunately it is only a GradeD/Level6 ;(

Things to know:

  • Remember what ever you are doing on the one side you are doing the opposite on both of the sides. (For Example: if you're adding on the left, you subtract from both, If you are multiplying on the left, you are dividing from both, and vice versa)
So lets get started :)

Examples
3x+1=13
-1        -1
3x=12
/3    /3 (dividing)
x=4

5x-3=27
+3     +3
5x=30
/5    /5
x=6

x/5+2=37
-2        -2
x/5=35
x5     x5
x=175

Here is 3 questions for you to try :)
1) 2x-3=13
2) 2x+4=10
3)4x-7=29
*Answers I will post in the next maths blog:)

Be sure to comment what you want me to do next :)
