Solve -2x - 15 = 6x + 9

 Solution:

Given equation: -2x - 15 = 6x + 9

In order to solve the equation, we need to isolate the variable.

By the transposing method,

Shifting 6x to left and -15 to right of equation

-2x - 6x = 9 + 15

-8x = 24

x = -24/8

x = -3

Solve -2x - 15 = 6x + 9

 Summary:

By solving -2x - 15 = 6x + 9, we get x = -3.
