Equations must be ​ (a)   . This means that what you do to one side of the equation, you ​ (b)   .

• balanced
• do to the other side
• equal
• long
• leave alone
• subtract from the other side

To solve a one step equation you: ​ (a)   , ​ (b)   , ​ (c)   , and ​ (d)   .

• circle the variable
• find the inverse operation
• preform the inverse operation to both sides
• solve
• move the variable over to the other side
• see what the operation is and leave it alone
• preform the operation you see

17 + x = 33

​ (a)  

17 + x = 33

-17 -17

​ (b)  

• the inverse operation is subtract
• x = 26
• the inverse operation is addition
• the inverse operation is multiplication
• x = 50
• x = 561

6x = 36
