Answer:
x = 20
Step-by-step explanation:
The three angles form a straight line so they add to 180 degrees
x+ 100 +3x = 180
Combine like terms
100+4x= 180
Subtract 100 from each side
100+4x-100= 180-100
4x= 80
Divide each side by 4
4x/4 = 80/4
x = 20
1st step you subtract 7 from both sides and the 7 get cancelled so you will get
2nd step you divide by 10 from both sides so you will get
3rd step is that you final answer is
