1.x/5-2=½(x-1) 2.2y-13=12-½y gimana carnya, plis jawab besok di kumpulin jam pertama lagi

1.
[tex] \frac{x}{5} - 2 = \frac{1}{2} ( \times - 1) \\ \\ 2x - 20 = 5( \times - 1) \\ 2x - 20 = 5x - 5 \\ 2x - 5x = - 5 + 20 \\ - 3x = 15 \\ x = - 5[/tex]
2.
[tex]2y - 13 = 12 - \frac{1}{2} y \\ 4y - 26 = 24 - y \\ 4y + y = 24 + 26 \\ 5y = 50 \\ y = 10[/tex]
