3.) 3x + y = -8

My answer: Y=-8 + -3x

4.)2x - y = 11
My Answer: y=2x + -11

5.) 4x + -8y = 24
My answer: y = 32x + -192

6.) 15x + 10 = -14 - 9x
My answer: NEED HELP WITH THIS ONE.

-1 is the last one

For #5: I first divided both sides by 4 to then be: x+(-2y)=6.My answer from there was 2y=x-6

For #6: I got -1 also

To solve the equation 15x + 10 = -14 - 9x, we can start by simplifying both sides of the equation:

15x + 10 = -14 - 9x

We can begin by combining like terms on each side. On the left side, we have 15x and -9x, which can be combined to give us 6x. On the right side, we have -14 and 10, which can be combined to give us -4:

6x + 10 = -14 - 4

Next, we can simplify further by combining the constants on each side of the equation:

6x + 10 = -18

To isolate the variable x, we need to get rid of the constant term on the left side. We can do this by subtracting 10 from both sides of the equation:

6x + 10 - 10 = -18 - 10

This simplifies to:

6x = -28

To solve for x, we can divide both sides of the equation by 6:

6x / 6 = -28 / 6

Simplifying further, we get:

x = -28 / 6

This can also be simplified as:

x = -14 / 3

Therefore, the solution to the equation 15x + 10 = -14 - 9x is x = -14/3.
