Answer:
x =2
Step-by-step explanation:
Solve for x:
6 - 4 x = 2 - 2 x
Add 2 x to both sides:
2 x - 4 x + 6 = (2 x - 2 x) + 2
2 x - 2 x = 0:
2 x - 4 x + 6 = 2
2 x - 4 x = -2 x:
-2 x + 6 = 2
Subtract 6 from both sides:
(6 - 6) - 2 x = 2 - 6
6 - 6 = 0:
-2 x = 2 - 6
2 - 6 = -4:
-2 x = -4
Divide both sides of -2 x = -4 by -2:
(-2 x)/(-2) = (-4)/(-2)
(-2)/(-2) = 1:
x = (-4)/(-2)
The gcd of -4 and -2 is -2, so (-4)/(-2) = (-2×2)/(-2×1) = (-2)/(-2)×2 = 2:
Answer: x = 2
