Solving Equations

General Rule:Whatever you do to one side of the = you must do exactly the same to the other side.

One Step Equations:~find the number on the same side of the equal sign as the variable~ do the inverse operation of that number (opposite operation, for example if it was +5 you would do -5) ~ whatever you did to one side of the equal sign do exactly the same to the other~ the number on the same side of the variable and its opposite cancel out, so you are left with just the variable~ the answer to the equation on the other side of the equal sign is the answer

Two Step Equations:~find the numbers that are on the same side as the variable~find the number without the variable next to it~do the inverse operation of that number ( for example, if it is -12, do +12)~ whatever you do to that number, do exactly the same to the other side of the equal sign~the number with its opposite cancel out, and you are left with the variable next to another number and the answer to the equation on the other side of the equal sign~do the inverse opperation of the number next to the variable (for example, if it is 2x, do 2/x)~once again, whatever you did to that number to exactly the same to the number on the other side of the equal sign~the number with its opposite cancel out, and you are left with whatever the variable equals

One Step Equations

Two Step Equations

------------------------------

x + 5 = 23 - 5 = -5-------------- x =18

__________________________

x = 20 5(5)=(5)----------x = 100

5x = 25 5 = 5______ x = 5

------------------------------------------------------------------------------------

x - 5 = 30 +5 = +5------------ x = 35

2x - 12 = 5 +12 = +12-------------- 2x = 17 2 = 2-------------- x = 8.5

x - 2 = 164 +2 = +2------------ x = 18 4 (4) (4)------------ x = 72
