Question 346967
2(w)+2(w+9)=186

Multiply 2 by each term inside the parentheses.
2w+2(w+9)=186

Multiply 2 by each term inside the parentheses.
2w+2w+18=186

Since 2w and 2w are like terms, add 2w to 2w to get 4w.
4w+18=186

Since 18 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 18 from both sides.
4w=-18+186

Add 186 to -18 to get 168.
4w=168

Divide each term in the equation by 4.
(4w)/(4)=(168)/(4)

Simplify the left-hand side of the equation by canceling the common factors.
w=(168)/(4)

Simplify the right-hand side of the equation by simplifying each term.
