Answer:
a.What three consecutive integers have a sum of 315? Which means that the first number is 104, the second number is 104 + 1 and the third number is 104 + Therefore, three consecutive integers that add up to 315 are 104, 105, and 106. We know our answer is correct because 104 + 105 + 106 equals 315 as displayed above
b. Step 1 Let no. be X
x/2+6=1+x
x+12/2=1+x
x+12=2+2x
X=10
I HOPE THIS IS HELPFUL

(a)
It is easy if we set the middle number as N, then we write an equation for N
(Because the +1, -1 cancells out eventually.)
(N-1) + N + (N+1) = 315
3N = 315
Therefore N=105 and three numbers are 104, 105, 106.
(b)
Set the number as N
6 is added to N over 2, and the result is N + 1
Now, we write an equation.
6 + N/2 = N + 1
12 + N = 2N + 2
-N = -10 (Now we change the sign.)
Therefore N = 10 and the number is 10.
