Question

17) Sum of two consecutive even numbers is 86. Find them.
(18) Sum of two consecutive odd numbers is 180. Find them.​

Answer 1

FIRST SUM ANSWER:

(x+2) +( x+4) = 86

x+x+2+4=86

2x+6 = 86

2x= 86- 6

2x = 80

x = 80/2

x= 40

so, x+2 = 40+2

=42

x+4 = 40+4

= 44

SECOND SUM ANSWER:

x+x+2= 180

2x= 180 - 2

2x= 178

x= 178/2

x = 89

so, x= 89

x+2= 89+2

= 91

Answer 2

Step-by-step explanation:

17) Let consecutive even numbers be x and x + 2

x + x + 2 = 86

2 x + 2 = 86

2 x = 86 - 2

2 x = 84

x = 42

The nos are 42 and 44

18) Let consecutive odd numbers be x and x + 2

x + x + 2 = 180

2 x + 2 = 180

2 x = 180 - 2

2 x = 178

x = 89

The nos are 89 and 91
