Slide 9 - Diapositive

Solving equations
When you need to solve an equation, we use inverse operations to isolate the variable
Inverse operations: 
+                       
-                      
⋅                      
/                      

Slide 10 - Diapositive

Solving equations
When you need to solve an equation, we use inverse operations to isolate the variable
Inverse operations: 
+                  
      -                       
⋅         /             
      ⋅           

x + 5 = 6
x + 5 - 5 = 6 - 5

Slide 11 - Diapositive

Inverse operations
  2x = 18 


Starter 1

Slide 12 - Diapositive

Inverse operations
  2x = 18 
2 ⋅ x = 18
2 ⋅ x ÷ 2 = 18 ÷ 2
x = 9

Starter 1

Slide 13 - Diapositive

Inverse operations
  x + 7 = 16


Starter 2

Slide 14 - Diapositive

Inverse operations
  x + 7 = 16
 x + 7 - 7 = 16 - 7
 x  = 9

Starter 2

Slide 15 - Diapositive

Inverse operations
Starter 3
10x=3

Slide 16 - Diapositive

Inverse operations
Starter 3
10x=3
10x10=310
x = 30

Slide 17 - Diapositive

Inverse operations
2x + 5 = 13 

Starter 4

Slide 18 - Diapositive

Inverse operations
2x + 5 = 13 
2x + 5 - 5 = 13 - 5
2x = 8
2 ⋅ x = 8
2 ⋅ x ÷ 2= 8 ÷ 2
x = 4
Starter 4
