Question

73•х+719=93812•(х-43)=516(х+19)-35=7025•х=100•25​

Answer 1

Ответ:

1) 73×x=938-719

73x=219

x=219/73=3

x=3

2)516+12x=516

12x=516+516

12x=1032

x=1032/12=86

x=86

3)(x+19)-35=70

x=70-19+35

x=86

4)25×x=100×25

25x=2500

x=2500/25=100

x=100

Answer 2

To solve the system of equations, let's go step by step:

1. 73•х + 719 = 93812•(х - 43)

To simplify this equation, let's distribute 93812 to the terms inside the parentheses:

73•х + 719 = 93812•х - 93812•43

Now, let's isolate the terms with "х" on one side and move the constant terms to the other side:

73•х - 93812•х = -93812•43 - 719

Combining like terms:

(-93739)•х = -4041748

Now, divide both sides of the equation by (-93739) to solve for "х":

х = (-4041748) / (-93739) х ≈ 43.128

2. 516(х + 19) - 35 = 7025•х

Let's simplify this equation:

516•х + 516•19 - 35 = 7025•х

516•х + 9804 - 35 = 7025•х

Combine like terms:

516•х - 7025•х = 35 - 9804

(-6509)•х = -9769

Divide both sides of the equation by (-6509) to solve for "х":

х = (-9769) / (-6509) х ≈ 1.501

3. 7025•х = 100•25

Divide both sides of the equation by 7025 to solve for "х":

х = (100•25) / 7025 х ≈ 3.567

Therefore, the solutions to the system of equations are: х ≈ 43.128, х ≈ 1.501, and х ≈ 3.567.
