Question

9 - 5(y + 2) = (7y - 5)(-3).​

Answer 1

Ответ:

9 - 5(y + 2) = (7y - 5)(-3).​

9-5y-10=-21y+15

-5y+21y=-9+10+15

16y=16

y=1

Answer 2

To solve the equation 9 - 5(y + 2) = (7y - 5)(-3), you'll want to follow these steps:

1. Distribute the -5 on the left side of the equation:

9 - 5y - 10 = (7y - 5)(-3)

2. Simplify both sides of the equation:

-1 - 5y = -21y + 15

3. Now, let's isolate the variable y. Add 5y to both sides of the equation to collect the y terms on one side:

-1 = -21y + 5y + 15

-1 = -16y + 15

4. Next, subtract 15 from both sides of the equation to isolate the -16y term:

-1 - 15 = -16y

-16 = -16y

5. Finally, divide both sides by -16 to solve for y:

(-16)/(-16) = y

y = 1

So, the solution to the equation is y = 1.
