Answer 3

To solve the equation -4x + 9 = -6x - 21, you'll want to isolate the variable x. Here are the steps to do that:

1. Start by adding 4x to both sides of the equation to get the x terms on one side: -4x + 4x + 9 = -6x + 4x - 21

Simplifying the equation: 9 = -2x - 21

2. Next, add 21 to both sides of the equation to isolate the term with -2x on the right side: 9 + 21 = -2x - 21 + 21

Simplifying further: 30 = -2x

3. Finally, divide both sides of the equation by -2 to solve for x: (30)/(-2) = (-2x)/(-2)

Simplifying the division: x = -15

So, the solution to the equation -4x + 9 = -6x - 21 is x = -15.
