Substitute both sides of the equation 
2(2x-5-4)=160-17
Distribute 
(2)(2x)+(2)(-5)+(2)(-4)=160+-17
4x+-10+-8=160+-17
Combine like terms 
(4x)+(-10+-8)=(160+-17)
4x+-18=143
4x-18=143
Add 18 to both sides 
4x-18+18=143+18
4x=161
Divide both sides by 4 
4x/4=161/4
x= 40.25 
I hope that's help ! Have a great day !
