Question

1) (39+x)-84=78 2) (x-83)+316=425 уравнения

Answer 1

1) (39+x)-84=78

    39+х=78+84

    39+х=162

    х= 162-39

    х=123

2) (x-83)+316=425

    х-83=425-316

    х-83=109

    х=109+83

    х=192

Answer 2

1) 39+х=78+84
39+х=162
х=162-39
х=123
2) х-83=425-316
х-83=109
х=109+83
х=192

Answer 3

1. To solve the equation (39 + x) - 84 = 78, we can follow these steps:

First, let's simplify the equation by combining like terms: 39 + x - 84 = 78

Next, let's simplify further by adding or subtracting terms: (39 - 84) + x = 78

Now, let's perform the subtraction operation within the parentheses: -45 + x = 78

To isolate x, we can subtract -45 from both sides of the equation: -45 + x - (-45) = 78 - (-45) x = 78 + 45 x = 123

Therefore, the solution to the equation (39 + x) - 84 = 78 is x = 123.

2. To solve the equation (x - 83) + 316 = 425, we can follow these steps:

First, let's simplify the equation by combining like terms: (x - 83) + 316 = 425

Next, let's simplify further by adding or subtracting terms: x - 83 + 316 = 425

To isolate x, we can subtract -83 and 316 from both sides of the equation: x - 83 + 83 + 316 - 316 = 425 - 83 - 316 x = 26

Therefore, the solution to the equation (x - 83) + 316 = 425 is x = 26.
