Ответ:
Решение:
- a) (y + 4) - (y - 1) = 6y
y + 4 - y + 1 = 6y
5 = 6y
\( y = \frac{5}{6} \) - б) 3p - 1 - (p + 3) = 1
3p - 1 - p - 3 = 1
2p - 4 = 1
2p = 5
\( p = \frac{5}{2} \)
\( p = 2,5 \) - в) 6x - (7x - 12) = 101
6x - 7x + 12 = 101
-x + 12 = 101
-x = 101 - 12
-x = 89
\( x = -89 \) - г) 20x = 19 - (3 + 12x)
20x = 19 - 3 - 12x
20x = 16 - 12x
20x + 12x = 16
32x = 16
\( x = \frac{16}{32} \)
\( x = 0,5 \)
Ответ: а) \(\frac{5}{6}\); б) 2,5; в) -89; г) 0,5.
