Answer:
3x+2x+a=180 degree(being linear pair)
5x+25=180
5x=180-25
x=155/5
x=31
Step-by-step explanation:
Let the four consecutive integers be
x , x+1, x+2, x+3
ATQ, Their sum is 18






<h3>Now,</h3>
- 1st number = x = 3
- 2nd number = x+1 = 3+1 = 4
- 3rd number = x+2 = 3+2 = 5
- 4th number = x+3 = 3+3 = 6
<em>The four numbers are 3,4,5,6 respectively and the smallest number among them is 3</em><em>.</em><em>.</em><em>.</em><em>~</em>
9n = 3n-12
-3n= -3n
6n= -12
divide by 6 = -2 =n
to check.. 9 times -2 = -18 soo.. 3 times -2= -6-12= -18
so it is correct!!
hope it helps :)
