Решите задачу:

$1)x + 3 = 5 \\ x = 5 - 3 \\ x = 2 \\ 2)y - 2 = 1 \\ y = 2 + 1 \\ y = 3 \\ 3)2x + 3 = 9 \\ 2x = 9 - 3 \\ 2x = 6 \\ x = 3 \\ 4)5y - 4 = 6 \\ 5y = 4 + 6 \\ 5y = 10 \\ y = 2 \\ 5) \frac{3}{7} + 4x = 1 \\ 4x = 1 - \frac{3}{7} \\ 4x = \frac{4}{7} \\ x = \frac{1 }{7} \\ 6)4 + 3y = 7 \\ 3y = 7 - 4 \\ 3y = 3 \\ y = 1$
