Welcome to Brainly!

Next time, please include the directions.  Here the directions would state, "Solve the following linear equation for x."


15-2x-8-3x=-x-12+4x+43

First:  combine like terms:  15 - 8 - 2x - 3x = 3x + 31 =>  7 - 5x = 3x + 31, or

8x = 24.

Next, solve the above result for x:  x = 24/8 = 3

The solution is x = 3.
