What is the inverse operation of addition? In other words, what operation would you use to solve this equation? x + 7 = 10

1 answer

The inverse operation of addition is subtraction. To solve the equation \( x + 7 = 10 \), you would subtract 7 from both sides of the equation.

Here’s how you do it step-by-step:

  1. Start with the equation: \( x + 7 = 10 \)
  2. Subtract 7 from both sides: \[ x + 7 - 7 = 10 - 7 \]
  3. This simplifies to: \[ x = 3 \]

So, the solution to the equation \( x + 7 = 10 \) is \( x = 3 \).
