Example Question - simple equation

Solving for a Variable in a Simple Equation

To solve for the blank, which I'll represent as x, in the equation \( x + 7 = 117 \), you'll need to isolate x on one side of the equation. This can be done by subtracting 7 from both sides of the equation: \( x + 7 - 7 = 117 - 7 \) This simplifies to: \( x = 110 \) Therefore, the number that fits in the blank to make the equation true is 110.
