Question

Помогите! Решить уравнения 1) 11x _ 6x + 17=2042 And 5 x + 3x _ 47=6401 _ (минус)

Answer 1

11х-6х+17=2042       5х+3х-47=6401
5х+17=2042               8х-47=6401
5х=2042-17                8х=6401+47
5х=2025                      8х=6448
х=2025/5                      х=6448/8
х=405                            х=806

Answer 2

1) 11x + 6x + 17 = 2042 Combine like terms: 17x + 17 = 2042 Subtract 17 from both sides: 17x = 2025 Divide both sides by 17: x = 119

2) 5x + 3x - 47 = 6401 Combine like terms: 8x - 47 = 6401 Add 47 to both sides: 8x = 6448 Divide both sides by 8: x = 806

So the solutions to the equations are: 1) x = 119 2) x = 806
