y = 4

Work Step by Step

To start this question, you need to distribute any numbers that can be distributed. In this case, they are 4 and -5. This gets you to the equation 4y + 9 = -15 + 10y. Here, you need to subtract 4y from both sides, and add 15 to both sides to get the variables alone. You should now have 6y = 24. At this point, you should divide both sides by 6 to get y alone, leaving you with y = 4.
