Identify the second step in solving this equation for y: -3(y + 6)=21
The equation given is -3(y + 6) = 21. We want to solve this equation for y. To find the value of y, we need to isolate y on one side of the equation.
Here's the step-by-step process:
1. Distribute the -3 across the parentheses: -3 * y + -3 * 6 = 21
Simplifying this, we get: -3y - 18 = 21
Now, we come to the second step, which is to isolate the term with y:
2. Add 18 to both sides of the equation to isolate the term with y:
-3y - 18 + 18 = 21 + 18
-3y = 39
After completing this second step, you'll move on to the third step, which is to solve for y by dividing both sides by the coefficient -3:
3. Divide both sides by -3:
-3y / -3 = 39 / -3
y = -13
So, y = -13 is the solution to the original equation.
