Answer 1

Ответ:

$2x + 4x + 18 = 90 \\ 6x + 18 = 90 \\ 6x = 90 = 18 \\ 6x = 72 \\ x = 12$

Answer 2

Ответ:

2х+4х+18=90

6х+18=90

6х=90-18

6х=72

Х=72:6

Х=12

Answer 3

To solve the equation 2x + 4x + 18 = 90, we can combine like terms on the left side of the equation:

2x + 4x + 18 = 90

Combining the x terms:

6x + 18 = 90

Now, we want to isolate the variable x. We can do this by subtracting 18 from both sides of the equation:

6x + 18 - 18 = 90 - 18

This simplifies to:

6x = 72

Next, we divide both sides of the equation by 6 to solve for x:

(6x)/6 = 72/6

This simplifies to:

x = 12

Therefore, the solution to the equation 2x + 4x + 18 = 90 is x = 12.
