Solving Equations… Always “I.I.S” an equation I (isolate) I (inverse) S (solve)

One-Step Equations: Addition Steps to find the solution Draw a line down the = sign Isolate the variable: Put a box around the variable Inverse the number OUTSIDE the box Solve it (Laws of Integers  “give me the finger”)

One-Step Equation: Subtraction Steps to find the solution Draw a line down the = sign Isolate the variable: Put a box around the variable Inverse the number OUTSIDE the box Solve it (Laws of Integers  “give me the finger”)

One-Step Equation: Multiplication Steps to find the solution: Draw a line down the = sign Isolate the variable: Put a box around the variable Inverse the number OUTSIDE the box “anytime there is a number, next to a variable, next to an equal sign, you always DIVIDE!”

One-Step Equation: Division Steps to find the solution: Draw a line down the = sign Isolate the variable: Put a box around the variable Inverse the number OUTSIDE the box “Circle it. Move it over. Multiply!”

Solving Two-Step Equations Steps to find the solution: Box in the coefficient and variable Perform the inverse operation to the number outside the box Solve it Perform the 2nd inverse operation (multiply? Divide?) Solve it!

Solving Multi-Step Equations… Draw the line down the = sign Left Column Right Column Do you need to apply the laws of integers? –(- ) - (+ ) neg* neg -> positive neg * positive -> negative Do you need to do the distributive property? Do you need to combine like terms? Did you box in the variable? Did you perform the inverse operation? Do you need to do it twice? Is the variable by itself? Is the number by itself? (yes -> then solve the equation) Do you need to get your Beyoncé’ on??? Inverse ALL variables to the LEFT!

Solving Equations: Word Problems Problem Solving 101: BUCK the Problem Did you box in the question? What will your variable be = what is the math unknown in the question? Did you go sentence by sentence and circle the “math stuff”? Did you scratch out EVERYTHING that is NOT circled? Did you T.T.P? (Translate. Put it on Top. Put it Together!) Did you SOLVE the equation?
