One Step Equation To solve one step equations, you have to use the inverse operation to get the variable alone. Example:

One Step Equations 1) x + 1 = 9 2) x + 3 = 5 3) x + -6 = 9 4) -32 = x + 3 5) 29 + x = 13

1) x + 1 = 9 2) x + 3 = x = 8 x = 2 3) x + -6 = 9 4) -32 = x (-6) -(-6) x = = x 5) 29 + x = x = -16 One Step Equations

One Step equation Word Problems 1)The Flash is trying to run 12 miles a night. He wants to run 156 miles. How many days will it take him to run that far? 2)How many super heroes can you buy with $12 if one costs $3? 3)Thor and his friend found some money buried in a field. They split the money evenly, each getting $ How much money did they find?

Two Step Equation First you do the inverse operation for addition and subtraction. Then you do the inverse operation for multiplication or division. Example: 3x+7= x=27 3/3 27/3 x = 9

Two Step Equations 1) 3h + 4 = 16 2) 2c – 7 = 21 3) k/4 + 9 = 21 4) m/3 – 5 = 22 5) b/2 + 7 = 21

Two Step Equation 1) 3h + 4 = 16 2) 2c – 7 = h = 12 2c = 28 3/3 12/3 2/2 28/2 h = 4 c = 14 3) k/4 + 9 = 21 4) m/3 – 5 = k/4 = 12 m/3 = 27 X4 X4 X3 X3 k = 48 m = 81 5) b/2 + 7 = b/2 = 14 X2 X2 b = 28

Two Step equation Word Problems 1) The Hulks mom took him shopping for some new clothes this past weekend. She purchased jeans and shirts. The jeans cost $45 each and the shirts cost $25 each. If she bought twice as many shirts as jeans, and she spent $190 on clothes for you, how many jeans and how many shirts did she buy? 2) Flash is 45. He is 15 years older than twice Spiderman’s age. How old is Spiderman? 3) Superman and Superwomen have a combined weight of 370 pounds. Superwomen weighs 155 pounds less than twice her Superman’s weight. How much does each of them weigh?

x=13 days

x=4 super heroes

x=$48.56

Hulks mom bought 2 pairs of jeans and 4 shirts for him this past weekend.

Spiderman is 15 years old

Superwomen weighs 175 pounds
