Answer:
y = 3
Step-by-step explanation:
9 - y = 2y
Step 1: Add y to both sides
9 - y + y = 2y + y
9 = 3y
Step 2: Divide both sides by 3
9 / 3 = 3y / 3
3 = y
Answer: y = 3
The value of y = 3
9 - y = 2y
Step 1: Add y to both sides
9 - y + y = 2y + y
9 = 3y
Step 2: Divide both sides by 3
9 / 3 = 3y / 3
3 = y
: y = 3
