To solve the equation, let's simplify and solve for y step by step:
Starting equation: 7y + 9 + 12 = -14y
Combine like terms on the left side:
7y + 21 = -14y
Add 14y to both sides to isolate the variable:
7y + 14y + 21 = 0
Combine like terms on the left side:
21y + 21 = 0
Subtract 21 from both sides:
21y = -21
Divide both sides by 21 to solve for y:
y = -21/21
Simplify the right side:
y = -1
Therefore, the solution to the equation is y = -1.

can u explain that in a not math genius way-

First you need to combine/add 9 and 12 because they're like terms, 7y is excluded. So, the answer is 21 7y + 21 = -14y And you have to put -14y in the middle of 7y and 21. 7y +14y + 21 = 0 Then again you need to combine/add the like terms. It's 7y + 14y = 21 Next, we'll isolate the term with y by subtracting 21 from both sides 21y + 21 - 21 = 0 - 21 Simplifying: 21y = -21 Finally, we'll solve for y by dividing both sides by 21: (21y)/21 = -21/21 Final answer: y = -1

Answer:
y = -1
Step-by-step explanation:
To solve the equation, let's simplify and solve for y step by step:
Starting equation: 7y + 9 + 12 = -14y
Combine like terms on the left side:
7y + 21 = -14y
Add 14y to both sides to isolate the variable:
7y + 14y + 21 = 0
Combine like terms on the left side:
21y + 21 = 0
Subtract 21 from both sides:
21y = -21
Divide both sides by 21 to solve for y:
y = -21/21
Simplify the right side:
y = -1
Therefore, the solution to the equation is y = -1.
7y + 21 = -14y
And you have to put -14y in the middle of 7y and 21.
7y +14y + 21 = 0
Then again you need to combine/add the like terms. It's 7y + 14y = 21
Next, we'll isolate the term with y by subtracting 21 from both sides
21y + 21 - 21 = 0 - 21
Simplifying:
21y = -21
Finally, we'll solve for y by dividing both sides by 21:
(21y)/21 = -21/21
Final answer: y = -1
