Solve for x:
60-8 x = 100
Subtract 60 from both sides:
(60-60)-8 x = 100-60
60-60 = 0:
-8 x = 100-60
100-60 = 40:
-8 x = 40
Divide both sides of -8 x = 40 by -8:
(-8 x)/(-8) = 40/(-8)
(-8)/(-8) = 1:
x = 40/(-8)
The gcd of 40 and -8 is 8, so 40/(-8) = (8×5)/(8 (-1)) = 8/8×5/(-1) = 5/(-1):
x = 5/(-1)
Multiply numerator and denominator of 5/(-1) by -1:
Answer: |x = -5
