Решите уравнение 7.43-1.28x=1.42x+5

7,43 - 1,28x = 1,42x + 5

7,43 - 5 = (1,42 + 1,28) x

2,43 = 2,7x

x = 2,43 : 2,7

х = 0,9

Проверка: 7,43 - 1,28*0,9 = 1,42*0,9 + 5

7,43 - 1,152 = 1,278 + 5

6,278 = 6,278

Ответ: {0,9}

7.43 + - 1.28x = 1.42x + 5

7.43 + - 1.28x = 5 + 1.42x

7.43 + - 1.28x = 5 + 1.42x

7.43 + - 1.28x + - 1.42x = 5 + 1.42x + - 1.42x

-1.28x + - 1.42x = - 2.7x 7.43 + - 2.7x = 5 + 1.42x + - 1.42x

1.42x + - 1.42x = 0.00 7.43 + - 2.7x = 5 + 0.00 7.43 + - 2.7x = 5

7.43 + - 7.43 + - 2.7x = 5 + - 7.43

7.43 + - 7.43 = 0.00 0.00 + - 2.7x = 5 + - 7.43 - 2.7x = 5 + - 7.43

x = 0.9
