The correct equation is n - 31 = 52
To check the solution, substitute 83 for the variable in the equation
This is an addition problem.
To solve the equation, add 31 to both sides.
Step-by-step explanation:
A number decreased by thirty-one is fifty-two
That means:
- Subtract 31 from a number
- The difference equal 52
Assume that the number is n
∵ The number is n
∵ When n decreased by 31 the answer is 52
∴ The equation is n - 31 = 52
The correct equation is n - 31 = 52
∵ n - 31 = 52
- To find n add 31 to both sides of the equation
∴ n - 31 + 31 = 52 + 31 ⇒ addition property
∴ n = 83
-To check the equation substitute n by 83 in the left hand side, the
answer must be equal the right hand side
∵ Left hand side = 83 - 31 = 52
∵ Right hand side = 52
∴ n = 83 is correct answer
To check the solution, substitute 83 for the variable in the equation
This is an addition problem.
To solve the equation, add 31 to both sides.
