Solve for x:
1/2 - x/3 = 5/6
Put each term in 1/2 - x/3 over the common denominator 6: 1/2 - x/3 = 3/6 - (2 x)/6:
3/6 - (2 x)/6 = 5/6
3/6 - (2 x)/6 = (3 - 2 x)/6:
(3 - 2 x)/6 = 5/6
Multiply both sides of (3 - 2 x)/6 = 5/6 by 6:
(6 (3 - 2 x))/6 = 6×5/6
6×5/6 = (6×5)/6:
(6 (3 - 2 x))/6 = (6×5)/6
(6 (3 - 2 x))/6 = 6/6×(3 - 2 x) = 3 - 2 x:
3 - 2 x = (6×5)/6
(6×5)/6 = 6/6×5 = 5:
3 - 2 x = 5
Subtract 3 from both sides:
(3 - 3) - 2 x = 5 - 3
3 - 3 = 0:
-2 x = 5 - 3
5 - 3 = 2:
-2 x = 2
Divide both sides of -2 x = 2 by -2:
(-2 x)/(-2) = 2/(-2)
(-2)/(-2) = 1:
x = 2/(-2)
The gcd of 2 and -2 is 2, so 2/(-2) = (2×1)/(2 (-1)) = 2/2×1/(-1) = 1/(-1):
x = 1/(-1)
1/(-1) = -1:
Answer: x = -1
Answer:
third angle = (-6x + 161)°
Step-by-step explanation:
180° = (x)° + (5x + 19)° + third angle →
180° = (6x + 19)° + third angle →
180° – (6x + 19)° = (6x + 19)° + third angle – (6x + 19)° →
180° – (6x + 19)° = third angle →
180° + -(6x + 19)° = third angle →
180° + (-6x)° + (-19)° = third angle
180° – 6x° – 19° = third angle
(180° – 19°) – 6x° = third angle
161° – 6x° = third angle
third angle = 161 – 6x°
third angle = -6x° + 161°
third angle = (-6x + 161)°
