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 : (

You are correct for the first part, you would be 16 and your Mom would be 44. After 8 years, you would be 24 and your mother would be 52. You solve the second part by adding 8 to 16 which equals 24. Then multiply 24 times 3 which equals 72. Lastly, subtract 20 from 72 to find your mother's new age. Which would be 52.

Hope this helps !
