How to solve equation?

Question

how do i solve the equation

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

4 equals 7x minus -1 divided by 8.

?

Answer 1

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

your statement is a bit ambiguous. I'll assume

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

-4 = 7x -  (1/8)

multiply by 8

-32 = 56x - 1

56x = -32 + 1

56x = -31

x = -31/56

but it could be

-4 = [7x - (-1)] / -8

multiply by -8

32 = 7x - (-1)

32 = 7x + 1

x = 31/7

.

Answer 2

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

-4=7x-1/8

-7x=-1/8+4

-7x=3.875

-7/-7x=3.875/-7

x= -31/56

Answer 3

you do -1 which eliminates the -1. then 3 divided by seven which is 0.4285713 then that number times 8. The answer is  27.405704.
