[(7x)-(-1)]/-8=

(7x+1)/-8=-4

7x+1=32 ... Cross multiplication

-1 -1

(7x)/7=31/7

x=31/7

You can check this value for x by plugging it into the original equation

[7*(31/7)-(-1)]/-8

(31+1)/-8

32/-8=-4

-4=-4

Asbury Park, NJ

7x - 1/8 = -4

get rid of the fraction by multiplying each term by 8:

56x - 1 = -32

add 1 to both sides to get:

56x = -31

divide both sides by 56 to get:

x = -31/56

Your Answer is, x = -31/56
