Hey there!
5y + 9 = 39
SUBTRACT 9 to BOTH SIDES
5y + 9 - 9 = 39 - 9
CANCEL out: 9 - 9 because that gives you
KEEP: 39 - 9 because that helps you solve for y
39 - 9 = 30
NEW EQUATION: 5y = 30
DIVIDE 5 to BOTH SIDES
5y/5 = 30/5
CANCEL out: 5/5 because that gives you 1
KEEP: 30/5 because that helps solve for y
y = 30/5
Answer: y = 6
Good luck on your assignment and enjoy your day!
