7x - 5 - 4/2 = 5x + 2/3
=> 7x - 7 = 5x + 2/3
=> 2x = 16/3
x = 16/6 = 8/3

7X - 7 = 5X + 2/3
7X - 7 2/3 = 5X
2X = 7 2/3 = 23/3 = 46/6
X = 23/6 = 3 5/6

it depends on whether the 7x - 5 - 4 is the numerator of the fraction with a denominator of 2 or not and if 5x + 2 is the numerator of the fraction with a denominator or 3..... use parenthesis to help with this.

7x-5-2=5x+2/3
7x-7=5x+2/3
2x=21/3+2/3
2x=23/3
x=46/3

anton you screwed it
7x-7=5x+2/3
7x-5x=2/3+7
2x=2/3+21/3
2x=23/3
x=23/6
try to answer better than this
