X=13; do you need the work? Also for future reference symbolab.com is where I get all my answers.

Let's find the slope (m) :
slope of given line is 5/3
now, let's plug the value of coordinates of a point lying on the line ( for example : (6 , 11) and slope (m) to find the y - intercept (c) :
value of y - intercept (c) = 1, so our equation will be :
