We are two integer brothers apart by 7 on the number line.if you take 5 times of me and add 2 times my brother you'll get 42. Can you find my value?
I believe there are two answer. ... first answer is 5x + 2(x+7)=42 therefore x=4 and 5(8)+2(1)=42
Both answers can be 4 & 11 or 8 &1. Pleade tell me if both are right or not
