If x=3(y+w)-1, what is the value of a in terms of x and y? w=x-3y/3 w=x-3y+1/3 w=-3y+1 w=x+1/9y i need only the options in the top .. is only one option

The options indicate that the question is to find the value of w in terms of x and y.

Given: x = 3(y + w) - 1

Expand the parenthesis (distgributive property) => x = 3y + 3w - 1

Transpose terms => 3w = x - 3y + 1

Divide by 3 => w = (x - 3y + 1) / 3

x = (x -3y + 1) / 3
