Help me i need help with this question its really hard pre test

A:280
60/15=4
X/70=4
70 times 4 = 280

Answer is A

Step-by-step explanation:

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
