Answer 2

`\bf{5(2x-1)=85}`

Divide both sides by 5.

• 
  `\bf{2x-1=(85)/(5) }`

Divide 85 by 5 to get 17.

• 
  `\bf{2x-1=17}`

Add 1 to both sides.

• 
  `\bf{2x=17+1}`

Add 17 and 1 to get 18.

• 
  `\bf{2x=18}`

Divide both sides by 2.

• 
  `\bf{x=(18)/(2) }`

Divide 18 by 2 to get 9.

• 
  `\bf{x=9 \ \ \to \ \ \ Answer}`

Verification

Let x = 9.

• 
  `\sf{5*(2*9-1)=85 \ \ \to \ \ \ Multiply }`

• 
  `\sf{5*(18-1)=85 \ \ \to \ \ \ [Subtract] }`

• 
  `\sf{5*17=85 \ \ \to \ \ \ [Multiply]}`
• 
  `\sf{85=85 \ \ \to \ \ \ [It \ is \ satisfied \ the \ equality]}`
