Answer 2

To solve the equation 2x + 3x = -2x - 13, we can simplify the equation and then isolate the variable x.

Starting with the given equation: 2x + 3x = -2x - 13

Combine like terms on both sides of the equation: 5x = -2x - 13

To isolate x, we want to get all the x terms on one side of the equation and the constant terms on the other side. We can do this by adding 2x to both sides of the equation: 5x + 2x = -2x + 2x - 13 7x = -13

Next, we'll isolate x by dividing both sides of the equation by 7: 7x/7 = -13/7 x = -13/7

Therefore, the solution to the equation 2x + 3x = -2x - 13 is x = -13/7.
