5y+9=3-7y ришэния пж

Answer 1

5у+9=3-7у
5у+7у=3-9
12у=-6
У=- 1/2

Answer 2

To solve the equation 5y + 9 = 3 - 7y, you need to isolate the variable y on one side of the equation. Follow these steps:

Step 1: Combine like terms on both sides of the equation. Add 7y to both sides: 5y + 7y + 9 = 3 - 7y + 7y

Simplify: 12y + 9 = 3

Step 2: Get rid of the constant term on the left side. To do this, subtract 9 from both sides of the equation: 12y + 9 - 9 = 3 - 9

Simplify: 12y = -6

Step 3: Finally, isolate y by dividing both sides by the coefficient of y (which is 12): 12y / 12 = -6 / 12

Simplify: y = -0.5

The solution to the equation is y = -0.5.
