Question

X+(x+1) + 2/3•(2x+1)=15

Answer 1

Ответ

икс равен 4

Объяснение:

раскрываем первые скобки , а потом вторые , т.е. 2/3*(2х+1)

далее складываем и получаем

2х+1+4/3х+2/3=15

2х+5/3+4/3x=15

6x+5+4x+45

10x+5=45

10x=40

x=4

=15

Умножим правую и левую части уравнения на 3

+3x+3x+3+4x+2=+45

3x + 3x + 4x = 45 – 2 – 3

10x = 40

x = 4

Answer 3

To solve the equation, we'll first simplify and then isolate the variable "x."

1. Distribute the fractions: 2/3 * (2x + 1) = 2/3 * 2x + 2/3 * 1 = (4x + 2)/3

2. Combine like terms: X + (x + 1) + (4x + 2)/3 = 15

3. Get rid of the fraction by multiplying both sides by 3 (the denominator of the fraction): 3 * (X + x + 1) + 3 * (4x + 2)/3 = 15 * 3

   This simplifies to: 3X + 3x + 3 + 4x + 2 = 45

4. Combine like terms again: 3X + 7x + 5 = 45

5. Move all terms involving "x" to one side of the equation: 3X + 7x = 45 - 5

   Simplifying further: 3X + 7x = 40

6. Now, isolate "x" on one side by moving the term "3X" to the other side. We do this by subtracting "3X" from both sides: 7x = 40 - 3X

7. Finally, divide both sides by 7 to solve for "x": x = (40 - 3X) / 7

And there you have the solution for "x" in terms of "X."
