Решите задачу:

$4-x = 5x + 22 -x - 5x = 22 - 4 -6x = 18 x = -3$

$5y + 18 = 8y 5y - 8y = -18 -3y = -18 y = 6$

$16 - 2x = 3x -2x - 3x = -16 -5x = -16 x = 3.2$

$42 - 2x = 5x -2x - 5x = -42 -7x = -42 x = 6$

$3x + 18 = 5x 3x - 5x = -18 -2x = -18 x = 9$

$5y - 22 = 3y 5y - 3y = 22 2y = 22 y = 11$

$3x+38=5x+18 3x - 5x = 18 - 38 -2x = -20 x = 10$

$7y - 5 = 3y + 3 7y - 3y = 3 + 5 4y = 8 y = 2$

$6x - 45 = 2x - 17 6x - 2x = -17 + 45 4x = 28 x = 7$

$3-3y=7-13y -3y + 13y = 7 - 3 10y = 4 y = 0,4$

$3x - 2 = 7 - x 3x + x = 7 + 2 4x = 9 x = 2.25$
