Question

3,5х + 1,4 × (х + 2,5) = 18, 2​

Answer 1

Ответ:

3,5х+1,4×(х+2,5)=18,2

3,5х+1,4х+3,5=18,2

4,9х+3,5=18,2

4,9х=18,2-3,5

4,9х=14,7

х=3

Answer 2

..................X=3...............

Answer 3

To solve the equation 3.5x + 1.4(x + 2.5) = 18.2, follow these steps:

1. Distribute the 1.4 on the left side of the equation:

   3.5x + 1.4x + 3.5 = 18.2

2. Combine like terms on the left side of the equation:

   4.9x + 3.5 = 18.2

3. Now, subtract 3.5 from both sides of the equation to isolate the term with x:

   4.9x = 18.2 - 3.5 4.9x = 14.7

4. Finally, divide both sides by 4.9 to solve for x:

   x = 14.7 / 4.9 x = 3

So, the solution to the equation is x = 3.

Answer 4

To solve the equation 3.5x + 1.4(x + 2.5) = 18.2, you can follow these steps:

1. Distribute the 1.4 on the left side of the equation: 3.5x + 1.4x + 3.5 = 18.2

2. Combine like terms on the left side of the equation: (3.5x + 1.4x) + 3.5 = 18.2 4.9x + 3.5 = 18.2

3. Subtract 3.5 from both sides of the equation to isolate the term with x: 4.9x + 3.5 - 3.5 = 18.2 - 3.5 4.9x = 14.7

4. Finally, divide both sides by 4.9 to solve for x: (4.9x)/4.9 = 14.7/4.9 x = 3

So, the solution to the equation is x = 3.
