Odpowiedź:
5/3 = 2(x + 1)/4 wstawić do 10 = 3x + 3
4 * 5 = 3 *2(x + 1)
20 = 6(x + 1)
20 = 6x + 6 | 2
10 = 3x + 3
5/4 = 2(x + 1)/3 wstawić do 8x + 8 = 15
5 * 3 = 4 * 2(x +1)
15 = 8(x + 1)
15 = 8x + 8
8x + 8 = 15
3/5 = 2x/4 wstawić do 5x = 6
3 * 4 = 5 * 2x
12 = 10x
10x = 12 | : 2
5x = 6
5/4 = 2x/3 wstawić do 8x = 15
3 * 5 = 4 * 2x
15 = 8x
8x = 15
