Here is a set of steps that leads to the solution.
It's not the only possible set of steps.
1). Multiply each side of the equation by 3 .
2). Divide each side of the equation by 2 .
3). Subtract 57 from each side of the equation.
The result of each step is:
1). 2(y + 57) = 534
2). y + 57 = 267
3). y = 210
