Solve the equations: \(\small \text{a}) \; x + 18 = 36 \\ \small \text{b}) \; y - 30 = 70 \\ \small \text{c}) \; 7 \times z = 49 \\ \small \text{d}) \; 96 \div m = 8 \)

Решение:

1. \( x + 18 = 36 \\ x = 36 - 18 \\ x = 18 \)
2. \( y - 30 = 70 \\ y = 70 + 30 \\ y = 100 \)
3. \( 7 \times z = 49 \\ z = 49 \div 7 \\ z = 7 \)
4. \( 96 \div m = 8 \\ m = 96 \div 8 \\ m = 12 \)

Ответ: а) x = 18; б) y = 100; в) z = 7; г) m = 12.
