One Step Equations and PEMDAS

Solve the equation
y - 4.1 = 5.4

• y = 9.5

• y = 5.9

• y = 4.1

• y = 5.4

Solve the equation
c - 21 = 45

• 66

• 62

• 24

• none of the above

Solve the equation

y + 8.3= 12.7

• 28

• 21

• 4.2

• 4.4

Solve the equation. 
54 = s + 34

• s= 10 

• s=20 

• s=34

• s=14

Solve for the equation
f - 22 = 36

• f= 62

• f= 14

• f=58

• f= 12

What property states that if you subtract the same number from both sides of an equation, the two sides will remain equal.    For example,  3+4 =  7   
               -4         -4
both sides equal 3!

• Addition property of equality

• Subtraction property of equality

• Multiplication property of equality 

• Commutative Property

Solve:
3(3x - 6) = 18

• x = 4

• x = -4

• no solution

• infinite solutions

What is the first step to complete when solving this equation?
10 - 3x = 4

• Subtract 10

• Add 10

• Add 3

• Divide by -3

The goal of solving a one, two, or multi-step equations is to:

• Find the constant

• Find the coefficient

• Find the value of the variable

• Guess and check
