First, multiply 4*2x-4*-5= 8x-20.
Second, add 15 to 8x-20
Third, that would equal 8x-20+15=11 
Fourth, 15+-20= -5 
Fifth, 8x-5=11
Sixth, add +5 to -5 and +5 to 11= 8x=16 
Last, do 8x/8x and 16/8x 
The answer is x=2

8x-20+15=11
8x+15=11+20
8x+15=31
8x=31-15
8x=16
X=2

First, add 20 to both sides
Simplify
Subtract 15 from both sides
Simplify
Divide 8 from both sides
