To solve the equation 2 + 4y = y - 7, we need to isolate the variable y on one side of the equation.
First, let's simplify by combining like terms on both sides of the equation.
On the right side, we have y - 7, and on the left side, we have 2 + 4y.
Combining like terms on the left side, we can add the 2 and 4y to get 4y + 2.
Therefore, the equation becomes 4y + 2 = y - 7.
Next, let's isolate the variable y by subtracting y from both sides of the equation.
4y + 2 - y = y - y - 7
Simplifying both sides of the equation, we get:
3y + 2 = -7
Now, let's isolate the variable y further by subtracting 2 from both sides of the equation.
3y + 2 - 2 = -7 - 2
Simplifying both sides of the equation, we get:
3y = -9
Finally, let's solve for y by dividing both sides of the equation by 3.
3y/3 = -9/3
Simplifying both sides of the equation, we get:
y = -3
Therefore, the solution to the equation 2 + 4y = y - 7 is y = -3.
Solve.
2+4y=y−7
