the answer I got was 59/40 but it doesn't seem right

x/8 - 3/2 = -1/40
Multiply both sides of the equation by 40:
5x - 60 = -1
Add 60 to each side:
5x = 59
Divide each side by 5:
x = 59/5
Hope that helps ;)

x/8 - 3/2 = - 1/40
40(x/8) - 40(3/2) = - 40(1/40)
5x - 60 = - 1
5x - 60 + 60 = - 1 + 60
5x = 59
5x/5 = 59/5
x = 59/5
x = 11 4/5
x = 11.8

x by 40:-
5x - 60 = -1
5x = 59
x = 59/5 = 11(4/5)

(x/8) - 3/2 = -1/40
x/8 = -1/40 + 3/2
x/8 = -1/40 + 60/40
x/8= -59/40
x= -472/40
x = -11.8

11.8 - of course that's the same as 59/5

x/8-3/2=-1/40
x/8=-1/40+3/2
x/8=-1/40+60/40
x/8=59/40
40x=8*59
x=8*59/40
x=11.8
