explanation: you have to use the distributive property to get rid of the 2 that is outside the parentheses. to do so, you would multiply the 2 to what is inside the parentheses and that would give you 4+2g.
First you will divide 100 by 50 you get 2. then you subrtact 38 from 50. you get 12. then since 100 is twice the amount as 50, you will multiply 12 by 2. you get 24. that is your answer
