Answer 2

Let's solve each equation step by step:

1. -5x + 10 = 2 + 3x

To solve for x, we need to simplify and isolate the x term on one side of the equation. Let's start by moving the constants to one side and the x terms to the other side:

-5x - 3x = 2 - 10

Combining like terms, we get:

-8x = -8

To solve for x, divide both sides of the equation by -8:

x = (-8)/(-8)

Simplifying further:

x = 1

So the solution for the first equation is x = 1.

2. 2(3x - 1) = -2 - 3x

Let's distribute the 2 on the left side of the equation:

6x - 2 = -2 - 3x

Next, let's move the x terms to one side and the constants to the other side:

6x + 3x = -2 + 2

Combining like terms, we get:

9x = 0

To solve for x, divide both sides of the equation by 9:

x = 0/9

Simplifying further:

x = 0

So the solution for the second equation is x = 0.

3. -15 = 6x - 9

To solve for x, let's isolate the x term by moving the constant to the other side:

6x = -15 + 9

Simplifying:

6x = -6

Divide both sides of the equation by 6:

x = (-6)/6

Simplifying further:

x = -1

So the solution for the third equation is x = -1.

In summary:

1. x = 1
2. x = 0
3. x = -1
