x-2+x+4+x+1=4
3x=4+2-4-1
3x=1
x=1/3
[tex]x - 2 = \frac{1}{3} - 2 = \frac{1}{3} - \frac{2}{1} = \frac{1}{3} - \frac{6}{3} = - \frac{5}{3} = - 1 \frac{2}{3} [/tex]
[tex]x + 4 = \frac{1}{3} + 4 = \frac{1}{3} + \frac{4}{1} = \frac{1}{3} + \frac{12}{3} = \frac{13}{3} = 4 \frac{1}{3} [/tex]
[tex]x + 1 = \frac{1}{3} + 1 = \frac{1}{3} + \frac{1}{1} = \frac{1}{3} + \frac{3}{3} = \frac{4}{3} = 1 \frac{1}{3} [/tex]
