Answer:
A . The numbers are 6 and 7, with the smaller number as 6
B. The number is 135
Step-by-step explanation:
A. Let the numbers be a and b
adding both gives 13
a + b = 13 •••••(i)
difference between the two is 1
b - a = 1 ••••••(ii)
So we have two equations that we can solve simultaneously;
b = 1 + a; Substitute this into 1
a + 1 + a = 13
2a + 1 = 13
2a = 13-1
2a = 12
a = 12/2
a = 6
b = a + 1 = 6 + 1 = 7
The numbers are 6 and 7 while 6 is the smaller number
B.Let the number be x
Divide by 5; x/5, then subtract 2 , we get 25
x/5 - 2 = 25
x/5 = 25 + 2
x/5 = 27
x = 5 * 27
x = 135
