Solve for y y+3=-y+9

$y + 3 = - y + 9$

Step 1

Move all terms containing $y$ to the left side of the equation.

Add $y$ to both sides of the equation.

$y + 3 + y = 9$

Add $y$ and $y$ .

$2 y + 3 = 9$

Step 2

Move all terms not containing $y$ to the right side of the equation.

Subtract $3$ from both sides of the equation.

$2 y = 9 - 3$

Subtract $3$ from $9$ .

$2 y = 6$

Step 3

Divide each term in $2 y = 6$ by $2$ and simplify.

Divide each term in $2 y = 6$ by $2$ .

$\frac{2 y}{2} = \frac{6}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 y}{2} = \frac{6}{2}$

Divide $y$ by $1$ .

$y = \frac{6}{2}$

Simplify the right side.

Divide $6$ by $2$ .

$y = 3$
