Answer 2

Given:
`\textsf{45 + x = 75}`

Need:
`\textsf{The value of the unknown x}`

Solution: In order to solve for the unknown we must subtract 45 from both sides which would isolate x and given us the value.

Subtract 45 from both sides

• 
  `\textsf{45 - 45 + x = 75 - 45}`

• 
  `\textsf{x = 75 - 45}`

• 
  `\textsf{x = 30}`

After simplifying the expression we were able to determine that x is equal to 30.
