Answer:
x= -5.4
Explanation:
10x-9x-11=6x+16 (the bracket is not necessary)
x-11=6x+16 (10x and 9x have the same variable so they can be subtracted)
x-6x-11=16 (we need to collect all the x at one side so shifting +6x to the other side of the equal sign will change the sign to -6x)
-5x-11= 16 (subtract the same variable and add the sign of the greater number)
-5x= 16+11 (we should leave the x alone so shifting -11 to that side will change its sign to +11)
-5x= 27 (both 16 and 11 have no variable so they can be added)
x= 27/-5 ( we only need x not any number with x if any number is there with x it means that it is getting multiplied with x for example 4x means 4 multiplied by x and if you shift anything that is getting multiplied then shifting means that it will change into divide)
x= -27/5 (the denominator can not have a - sign so we will shift the sign into the numerator)
x= -5.4
