Given 2y = 5(3 + y):
You’ll have to solve for y:
Start by distributing 5 into (3 + y):
2y = 5(3 + y)
2y = 15 + 5y
Subtract 15 from both sides:
2y - 15 = 15 - 15 + 5y
2y - 15 = 5y
Then, subtract 2y from both sides:
2y - 2y - 15 = 5y -2y
-15 = 3y
Then , divide both sides by 3 to solve for y:
-15/3 = 3y/3
-5 = y
Therefore, y = -5
