Answer: Yes
Step-by-step explanation: Here, we want to decide if 3 is a solution for the equation 2n - 6 = 5n - 15. We can do this by simply plugging in 3 for n. If the statement holds true when 3 is plugged in for n, then 3 is a solution.
Plugging in 3 for n, we have 2(3) - 6 = 5(3) - 15.
2(3) is equal to 6 and if we subtract 6 we get 0.
On the right side, 5(3) is equal to 15 and if we subtract 15 we get 0.
0 = 0 is a true statement so yes,
3 is a solution for the equation 2n - 6 = 5n - 15
