Step-by-step explanation:
Answer:
x=30
Step-by-step explanation:
The two angles are supplementary. They add to 180
4x+20 + 40 =180
Combine like terms
4x+60 =180
Subtract 60 from each side
4x+60-60 = 180-60
4x = 120
Divide each side by 4
4x/4 = 120/4
x = 30
The original number is 24
2 x 3 = 6
6 x 4 = 24
or
24 / 4 = 6
6 / 3 = 2
