The solution is x = -25/12x=2512

Explanation:

Given (x+5)/5=1-((x+5)/7)x+55=1(x+57)

Multiply both sides by 35:

7(x+5)=35-5(x+5)7(x+5)=355(x+5)

Distribute the 7 and the -5:

7x+35=35-5x-257x+35=355x25

Add 5x-355x35 to both sides:

12x=-2512x=25

x = -25/12x=2512

rarr(x+5)/5=1-(x+5)/7x+55=1x+57

rarr(x+5)/5+(x+5)/7=1x+55+x+57=1

rarr(x+5)[1/5+1/7]=1(x+5)[15+17]=1

rarr(x+5)[12/35]=1(x+5)[1235]=1

rarrx=35/12-5=-25/12x=35125=2512
