1.) 2/5 (x+4) = 3/5x-2 2.) 5/6 (x+2)=1/2x-2 maka nilai x-2 adalah 3.) 3x+1/14 - 1-2x/2=2 Tolong yah bantu pakai cara:(

[tex]1. \frac{2}{5} (x + 4) = \frac{3}{5}x - 2 \\ \frac{2}{5} x + \frac{8}{5} = \frac{3}{5} x - 2 \\ \frac{3x - 2x}{5} - 2 - \frac{8}{5} = 0 \\ \frac{x}{5} - \frac{10}{5} - \frac{8}{5} = 0 \\ x - 18 = 5 \\ x = 23 \\ \\ 2. \ \frac{5}{6} (x + 2) = \frac{1}{2} x - 2 \\ \frac{5x + 10}{6} = \frac{x}{2} - 2 \\ 5x + 10 = \frac{6x}{2} - 12 \\ 5x + 10 = 3x - 12 \\ 5x - 3x + 10 + 12 = 0 \\ 2x + 22 = 0 \\ 2x = - 22 \\ x = - 11 \\ soal = x - 2 = - 11 - 2 = - 13 \\ \\ 3. 3x+ \frac{1}{14} - 1 - \frac{2x}{2} = 2 \\ 3x + \frac{1}{14} - \frac{14}{14} - x = 2 \\ 2x - \frac{13}{14} = 2 \\ 2x = 2 + \frac{13}{14} \\ 2x = 2+ \frac{13}{14} \\ 2x = \frac{28}{14} + \frac{13}{14} \\ 2x = \frac{41}{14} \\ x = \frac{41}{28} [/tex]
