Q. Which value of k makes 5−k+12=16 a true statement?Choose 1 answer:(A) k=1(B) k=2(C) k=3(D) k=4
Simplify left side of equation: First, simplify the left side of the equation by combining like terms 5 and 12.5−k+12=16(5+12)−k=1617−k=16
Isolate k on one side of equation: Next, to find the value of k, we need to isolate k on one side of the equation. We can do this by subtracting 17 from both sides of the equation.17−k−17=16−17−k=−1
Solve for k: Finally, to solve for k, we need to multiply both sides of the equation by −1 to get the positive value of k.−k×−1=−1×−1k=1
