Solving multi-step equations!

Page 1

Solving Equations! ( aka solving a mystery!)

What are one step equations? How do they look? What are the four basic operations?

One step means you have to do only one thing to find an answer! Oh, to stay that simple!

One Step Equations

What are the four basic operations?

Add

Subtract

Multiply

Divide

How does an equation with addition look?

Page 3

How does an equation with subtraction look?

Page 4

How does an equation with multiplication look?

Page 5

How does an equation with division look?

Page 6

How do two step equations look? What makes them different? (besides another step????)

The difference is the variable term has now been multiplied or divided AND also has a number either added to or subtracted from it

Page 7

In the picture below, how is the x combined with the 9? How is the 3 combined with the 9x?

In the picture below, how is the x combined with the 3? How is the 12 combined with the variable term?

IMPORTANT!!!! In two step equations, take care of anything added to or subtracted from first!!!!!

More than Two Steps!

look for parenthesis to see is you need the distributive property

if you see them, distribute ( which means multiply two times)

once you multiply, check for like terms (what does that mean?)

combine like terms ON THE SAME SIDE FIRST - if you have any SAME SIDE KEEP SAME SIGN ALREADY THERE

combine like terms on opposite side SECOND - CHANGE SIDES CHANGE SIGNS

the last step will be to divide or to multiply
