Answer:
To solve the equation XX/2-6=-18, we need to isolate the variable on one side of the equation. First, we can add 6 to both sides of the equation to eliminate the constant term on the left side: XX/2-6+6=-18+6 Simplifying the left side, we get: XX/2=-12 Next, we can multiply both sides by 2 to eliminate the fraction: 2*(XX/2) = 2*(-12) Simplifying the left side, we get: XX = -24 Therefore, the value of XX that satisfies the equation is -24.
