How do you write negative seven minus the product of 5 and a number is 28?

To solve the expression "negative seven minus the product of 5 and a number is 28", we need to translate it into a mathematical equation and solve for the unknown number.
Let's assume the unknown number is represented by 'x'. The equation would be: -7 - (5x) = 28.
To isolate 'x', we need to get the expression with 'x' on one side of the equation. To do this, we can add 7 to both sides of the equation: -7 + 7 - (5x) = 28 + 7 - (5x). This simplifies to -5x = 35.
Finally, to solve for 'x', we divide both sides of the equation by -5: -5x / -5 = 35 / -5. This gives us x = -7. Therefore, the unknown number is -7.
