Solve for y 6(y+3)-5y=15

$6 (y + 3) - 5 y = 15$

Step 1

Simplify $6 (y + 3) - 5 y$ .

Simplify each term.

Apply the distributive property.

$6 y + 6 \cdot 3 - 5 y = 15$

Multiply $6$ by $3$ .

$6 y + 18 - 5 y = 15$

Subtract $5 y$ from $6 y$ .

$y + 18 = 15$

Step 2

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

Subtract $18$ from both sides of the equation.

$y = 15 - 18$

Subtract $18$ from $15$ .

$y = - 3$
