5 \( c+6=-7 \)

To solve for \( c \), you’ll want to isolate it on one side of the equation. Start by subtracting 6 from both sides: \( c = -7 - 6 \). That gives you \( c = -13 \). See? Just a bit of simple arithmetic to find the missing number! In math, dealing with equations is like playing detective; you're uncovering the value that makes everything work. This technique of isolating the variable is vital—you'll use it for countless equations across geometry, algebra, and beyond. Keep practicing, and soon you’ll solve these mysteries in no time!
