Does Devin like cleaning Brittany's pipes?
175(x+y)=5200
y=2x+7
175(x+2x+7)=5200
525x+1225=5200
525x=3975
x=3975/525 or 5.5714
im probably wrong tho as i just skimmed through it but check my work and see if its right
edit: this gives you the devin's hourly rate i think... i hate math -.-

well im really not sure this is right, answer doesnt really make sense. i guess its 175/2*5.5714 if they both worked the same amount of hours... dumb problem
I would say 1731. bcause 1731 x2+7= 3469 and 3469+1731=5200 thanks if help @noob555
