Question

−18−9x=138+3x. срочно!

Answer 1

Ответ: Х= -13

Пошаговое объяснение:

-18 - 9х = 138 + 3х

-9х - 3х = 138 + 18

-12х = 156

х = -13

Ответ: Х= -13

Answer 2

Пошаговое объяснение: в одну сторону с (x) в другую  с (Y)

тоесть, 9x+3x=-18-138(минус потому что после равно он всегда вроде ставиться

Потом 9х+3х = 12х

а -18-138 =-156

и потом дели

12х =-156

х=(дели эти числа12х =-156 и получишь ответ)

Answer 3

To solve the equation −18 − 9x = 138 + 3x, follow these steps:

Step 1: Combine like terms Move the variable terms (−9x and 3x) to one side of the equation and the constant terms (−18 and 138) to the other side. To do this, you can add 9x to both sides and subtract 138 from both sides:

−18 − 9x + 9x = 138 + 3x + 9x

Simplifying the left side, the −9x and +9x cancel out:

−18 = 138 + 12x

Step 2: Isolate the variable Next, isolate the variable term (12x) by subtracting 138 from both sides:

−18 − 138 = 138 + 12x − 138

Simplifying both sides:

−156 = 12x

Step 3: Solve for x Finally, solve for x by dividing both sides by 12:

x = −156 / 12 x = -13

The solution to the equation is x = -13.
