Identify the second step in solving this equation for y : −3(y + 6) = 21 . (1 point)
Add 6 to both sides.
Add 6 to both sides.
Divide both sides by −3
.
Divide both sides by negative 3.
Divide both sides by 6.
Divide both sides by 6.
Subtract 6 from both sides.
Divide both sides by -3.
The second step in solving the equation −3(y + 6) = 21 is to divide both sides by -3.
Explanation:
To solve for y, we need to isolate y on one side of the equation. In this case, the term that is multiplied by y is -3. To remove -3 from the equation, we divide both sides by -3.
By dividing -3(y + 6) by -3, the -3 on the left side of the equation cancels out, leaving us with y + 6. On the right side, we divide 21 by -3, which gives us -7.
Therefore, the second step in solving the equation −3(y + 6) = 21 is to divide both sides by -3.
