`\large\text{Whenever you see or hear the word \underline{decrease} in mathematics it usually}\\\large\text{means \underline{SUBTRACT} , so you are taking away a number. You are usually going}\\\large\text{\underline{DOWNWARD}}`

`\large\text{The phrase \underline{a number} usually means that you have an \underline{unknown variable}}`

`\large\text{Now that have that little GUIDE for you to follow by for this equation,}\\\large\text{lets ANSWER your given equation}`

`\large\text{We can say your unknown variable is going to be labeled as \bf s}`

`\large\text{REMEMBER we said that DECREASED means subtract or taking}\\\large\text{away!}`

`\large\text{Seven will simply be 7 because you have that information already}\\\large\text{in your algebraic expression}`

`\large\text{Based on the given information we did, we have reached your answer}`

`\large\text{= \bf s - 7}`

`\boxed{\boxed{\large\text{Answer: \huge \bf s - 7}}}\huge\checkmark`
