The way we simplify this is by using the distributive property and multiply every term by 0.5. When we do this we get 2a+3b
Given parameters:
Weight of Tan = 146pounds
Unknown:
Weight of Minh = ?
Following this problem step wisely, we can derive a solvable algebraic equation;
Let the weight of Minh = M
In the second sentence, we see that Minh weighs 15pounds more than Tan;
So;
M = 15 + Weight of Tan
Since we already know the weight of Tan,
Weight of Minh = 15 + 146 = 161pounds
We clearly see that Minh's weight will be 161 pounds.
D), I believe it is -42. Correct me if im wrong :}
