To write and solve the equation based on the statement "A number decreased by thirty-one is fifty-two," we can define the unknown number as \( x \).
Step 1: Write the Equation
The equation based on the problem is:
\[ x - 31 = 52 \]
Step 2: Solve the Equation
To solve for \( x \), we need to isolate \( x \) on one side of the equation. We do this by adding 31 to both sides:
\[ x - 31 + 31 = 52 + 31 \]
\[ x = 83 \]
Step 3: Check the Solution
To verify our solution, we will substitute \( x = 83 \) back into the original equation:
- The original equation is \( x - 31 = 52 \).
- Substitute \( 83 \) in for \( x \):
\[ 83 - 31 = 52 \] \[ 52 = 52 \]
This confirms that our solution is correct.
Summary
- Equation: \( x - 31 = 52 \)
- To solve the equation, add 31 to both sides of the equation.
- To check the solution, substitute \( 83 \) for the variable in the equation.
