I probably am wrong but it might be 50.27 in
You could solve it with these two steps:
#1). Subtract 6 from each side of the equation.
and then
#2). Divide each side by 7.
If you'll do that, the solution will be right there on the paper in front of you.
It'll begin with "x =", and right after that will be the value of 'x'.
Could you zoom out a little maybe? it looks like you cut off something in front of dot
