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.
