Q. A set of 3 consecutive integers adds up to 42. What are the integers?_____, _____, _____
Define Integers: Let x be the first integer. The three consecutive integers can be represented as x, x+1, and x+2.
Set Up Equation: Set up the equation to represent the sum of the three consecutive integers equal to 42: x+(x+1)+(x+2)=42.
Simplify Equation: Simplify the equation: x+x+1+x+2=42. Combine like terms: 3x+3=42.
Isolate Variable Term: Isolate the variable term by subtracting 3 from both sides of the equation: 3x+3−3=42−3. This simplifies to 3x=39.
Divide to Solve: Divide both sides of the equation by 3 to solve for x: 33x=339. This gives us x=13.
Find Consecutive Integers: Now that we have the value of x, we can find the three consecutive integers: x, x+1, and x+2. Substitute x with 13: 13, 13+1, 13+2. This gives us the integers 13, x0, x1.
