295. Сравни уравнения каждой пары и их решения. x+75 = 125 x-75 = 125 x. 10 = 250 x: 10 = 250 x: 7 = 140 140: x=7 32: x=32 32.x = 32

1. x + 75 = 125; x = 125 - 75; x = 50; x - 75 = 125; x = 125 + 75; x = 200.
2. x × 10 = 250; x = 250 : 10; x = 25; x : 10 = 250; x = 250 × 10; x = 2500.
3. x : 7 = 140; x = 140 × 7; x = 980; 140 : x = 7; x = 140 : 7; x = 20.
4. 32 : x = 32; x = 32 : 32; x = 1; 32 × x = 32; x = 32 : 32; x = 1.

Ответ: 50 и 200; 25 и 2500; 980 и 20; 1 и 1.
