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
