Answer:
x=11
Explanation:
(5x-3x)-3-8=2x+8-8
NOTE: when you add the -3-8 and maintain the sign - sign number
unless it appears like this 3--8
2x-11=2x
then you group like terms
2x-2x=11
NOTE: when a a positive number crosses the equal to sign it becomes negative and the vice versa for the negative sign
x=11
NOTE: 2x-2x is not the same as 2s-2x
