 Combine like terms: -26x + 34x = 8x 20 + 8x = 60 + -34x + 34x 
 Combine like terms: -34x + 34x = 0 20 + 8x = 60 + 0 20 + 8x = 60 
Add '-20' to each side of the equation. 20 + -20 + 8x = 60 + -20 
 Combine like terms: 20 + -20 = 0 0 + 8x = 60 + -20 8x = 60 + -20 
 Combine like terms: 60 + -20 = 40 8x = 40 
 Divide each side by '8'. x = 5 
 Simplifying x = 5
