Question

1) 3Х+8-Х=50 2)180-2Х+4Х=200

Answer 1

Ответ:

1. х = 21

2. х = 10

Пошаговое объяснение:

1) 3Х+8-Х=50

2х = 50 - 8

2х = 42

х = 42/2

х = 21

2)180-2Х+4Х=200

2х = 200 - 180

2х = 20

х = 20/2

х = 10

Answer 2

To solve these equations, you'll need to isolate the variable x. Let's work through them one by one:

1. 3x + 8 - x = 50

First, combine like terms on the left side of the equation:

3x - x + 8 = 50

Now, simplify:

2x + 8 = 50

Next, subtract 8 from both sides to isolate 2x:

2x = 50 - 8 2x = 42

Now, divide both sides by 2 to solve for x:

2x/2 = 42/2 x = 21

So, the solution to the first equation is x = 21.

2. 180 - 2x + 4x = 200

First, combine like terms on the left side of the equation:

(-2x + 4x) + 180 = 200

Now, simplify:

2x + 180 = 200

Next, subtract 180 from both sides to isolate 2x:

2x = 200 - 180 2x = 20

Now, divide both sides by 2 to solve for x:

2x/2 = 20/2 x = 10

So, the solution to the second equation is x = 10.

Therefore, the solutions are:

1. x = 21
2. x = 10
