Question

3x-0,09=0,81+2,4x (2x+0,1)-10=1

Answer 1

Ответ:

x=1,5

x=5,45

Объяснение:

1)3x-0,09=0,81+2,4x

3x-2,4x=0,81+0,09

0,6x=0,9

x=1,-5

2)(2x+0,1)-10=1

2x+0,1-10=1

2x-9,9=1

2x=1+9,9

2x=10,9

x=5,45

Answer 2

To solve the given equations, let's take them one by one:

1. 3x - 0.09 = 0.81 + 2.4x

Step 1: Combine the x terms on one side and the constant terms on the other side.

Group the x terms on the left side: 3x - 2.4x = 0.81 + 0.09

Step 2: Simplify the equation:

0.6x = 0.9

Step 3: Solve for x:

x = 0.9 / 0.6

x = 1.5

So the value of x in the first equation is x = 1.5.

2. (2x + 0.1) - 10 = 1

Step 1: Combine the constant terms on one side:

2x + 0.1 - 10 = 1

Step 2: Simplify the equation:

2x - 9.9 = 1

Step 3: Move -9.9 to the other side by adding it:

2x = 1 + 9.9

Step 4: Simplify further:

2x = 10.9

Step 5: Solve for x:

x = 10.9 / 2

x = 5.45

So the value of x in the second equation is x = 5.45.

To summarize:

1. x = 1.5
2. x = 5.45
