Answer 1

Решение

$1)\\ x=\frac{2}{3} x+1.\\ 3x=2x+3.\\ x=3.\\ 2)\\ x-\frac{1}{2}=\frac{3}{4}x .\\ 4x-2=3x\\ 4x-3x=2. => x=2.\\ 3)\\ x-\frac{2}{3} =\frac{5}{6} x.\\ 6x-4=5x.\\ 6x-5x=4. => x=4.\\ 4)\\ 1\frac{4}{5} y=y+4.\\ \frac{9}{5}y=y+4.\\ 9y-5y=20.\\ 4y=20. => y=5.\\ 5)\\ \frac{2}{3} y-\frac{1}{3} =\frac{5}{9}y.\\ 6y-3=5y.\\ 1y=3. => y=3.\\ 6)\\ \frac{3}{4} y-\frac{2}{3} =\frac{7}{12}y.\\ 9y-8=7y.\\ 9y-7y=8\\ 2y=8. => y=4.$
