Question

5y+9=3-7y верны ответ

Answer 1

$5y + 9 = 3 - 7y$

$5y - 7y = 3 - 9$

$12y = - 6$

$y = \frac{1}{2}$

$y = - 0.5$


Удачи!Надеюсь помогла!

Answer 2

Итак, переносим слагаемое в другую часть уравнения.Затем привести подобные и вычислить. Разделить обе части на 12
Ответ: - 0,5

Answer 3

Let's solve the given equation for the variable "y":

5y + 9 = 3 - 7y

Step 1: Combine the "y" terms on one side and the constants on the other side.

To do this, let's move the "-7y" term to the left side by adding 7y to both sides of the equation:

5y + 7y + 9 = 3 - 7y + 7y

Simplify the equation:

12y + 9 = 3

Step 2: Isolate the variable term on one side by moving the constant term to the other side. To do this, subtract 9 from both sides:

12y + 9 - 9 = 3 - 9

Simplify the equation:

12y = -6

Step 3: Solve for "y" by dividing both sides by 12:

y = -6 / 12

Simplify the division:

y = -1/2

So, the solution to the equation is y = -1/2.
