ok first thing is to make (x-7) a fraction by placing it over 1
we can do this because %28x-7%29%2F1 equals %28x-7%29
Now the equation looks like this:
%28%28x-7%29%2F1%29%2A%282%2F3%29=25
Next multiply the numerator of each fraction and the denominator of fraction
%282x-14%29%2F3=25
Now multiply each side of the equal sign by 3
3%2A%28%282x-14%29%2F3%29=25%2A3
2x-14=75
Next add 14 to both sides of the equal sign
2x-14%2B14=75%2B14
2x=89
Now to solve for x divide both sides of the equal sign by 2
2x%2F2=89%2F2
x=44.5
