5. Solve these equations using the guess and check method. h + 21 = 38

b) S-17 = 23

$ c) g + 28 = 50 d)

2x + 18 = 42 e)

f) 3p + 24 = 57

g) 7+-5=2

-=2 49 - 17 = 19

h) En + 15 = 17

k) :+9 = 12 1

i) + 18 = 33 5 32 + LU-8 = 0 j e2+9= 34 ] 0 34

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
