My mother is 12 years more than twice my age. after 8 years she will be 20 years less than three times my my age and my mothers age

i have this equation:
2x+12+8=3x-20
2x+12-12+8-8=3x-20-20
2x+3x=-40
5x/5=-40/5
x=-8
need pls : (

answer: sorry

step-by-step explanation: can you tell me pls how to find the rational of two integers

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
