Solve. - 2 (6 - 20n) = 20 (2n - 3)

a. 40

b. 36

c. no solution

d. all real numbers

-2 (6-20n) = 20 (2n-3)

-12 + 40n = 40n - 60

40n = 40n - 60 + 12

40n - 40n = 60 + 12 (dont minus 40n - 40n yet, we can factorise it)

n (40-40) = 60 + 12

n = (60 + 12) / (40-40)

n = 60 + 12 / 0

Therefore no solution as we cannot divide by 0
