Identify the second step of this equation y:-3(y+6)=21

3 answers

The second step of the equation would be to distribute the -3 on the left-hand side of the equation:

y:-3 * y + (-3) * 6 = 21

which simplifies to:

-3y - 18 = 21
Add 6 to both sides
Subtract 6 from both sides
Divide both sides by -3
Divide both sides by -6
To solve the equation step by step:

1. Distribute the -3 on the left-hand side:
-3y - 18 = 21

2. Add 18 to both sides:
-3y - 18 + 18 = 21 + 18
-3y = 39

3. Divide both sides by -3:
(-3y) / (-3) = 39 / (-3)
y = -13

So the solution to the equation y: -3(y+6) = 21 is y = -13.
