Answer:

x = (-5)/9

Step-by-step explanation:

Solve for x:

(-9 x)/8 - 5/8 = 0

(-9 x)/8 - 5/8 = (-9 x - 5)/8:

(-9 x - 5)/8 = 0

Multiply both sides of (-9 x - 5)/8 = 0 by 8:

(8 (-9 x - 5))/8 = 8×0

(8 (-9 x - 5))/8 = 8/8×(-9 x - 5) = -9 x - 5:

-9 x - 5 = 8×0

0×8 = 0:

-9 x - 5 = 0

Add 5 to both sides:

(5 - 5) - 9 x = 5

5 - 5 = 0:

-9 x = 5

Divide both sides of -9 x = 5 by -9:

(-9 x)/(-9) = 5/(-9)

(-9)/(-9) = 1:

x = 5/(-9)

Multiply numerator and denominator of 5/(-9) by -1:

Answer: x = (-5)/9
