To solve the equation described, we can break down the problem step by step. The statement says that four times the difference of a number (let’s call it x) and 7 is equal to 12. We can express this mathematically as:
4(x – 7) = 12
Now, let’s solve for x:
- First, divide both sides of the equation by 4 to isolate the term inside the parentheses:
- Next, add 7 to both sides to solve for x:
- This simplifies to:
x – 7 = 3
x = 3 + 7
x = 10
Therefore, the number you are looking for is 10. To verify, you can plug it back into the original equation:
4(10 – 7) = 12, which simplifies to 4(3) = 12, confirming that our solution is correct.
