Question

Which value in the replacement set is a solution to this equation? 4n−11=9 Replacement set: {4, 5, 6} Drag the solution into the box.

A. 4
B. 5
C. 6

Answer 1

Answer will be B. 5. 4n - 11 = 9 -> 45 - 11 = 9

Answer 2

To solve the equation, we can first collect like terms to make the process easier.
4n-11=9 -> +11 on both sides -> 4n=20
Now, we can see that 4 n's make 20, so we can work backwards to solve for n:
4n=20 -> ÷4 on both sides -> n=5
So, your answer is B - 5.
