Lesson 1: One-Step Equations

Slide 2: 

EX x + 2 = 7 -2 -2 x = 5

Slide 3: 

EX x – 8 = 4 +8 +8 x = 12

Slide 4: 

EX -5x = 30 -5 -5 x = -6

Slide 5: 

EX 3 · · 3 x = 18

Slide 6: 

EX 1 9 x = -45

Slide 7: 

EX Michael withdrew $50 from his bank account. His balance after the withdrawal was $315.23. Write and solve an equation to find Michael’s previous balance. previous balance – withdrawal = new balance Let x = previous balance x – 50 = 315.23 +50 +50 x = 365.23
