ATQ
Adding both
Now putting value in eq(2)
For this problem, we will take the given information and use it to create an expression representing the problem. We want the expression to equal the amount Dylan has.
Let's start by defining a variable.
d=dollars Leo has
We know that Dylan has 3 more dollars than twice the amount Leo has. We can take this information and create our expression.
2d+3 is our expression.
We multiply our variable by 2 and then add 3 since Dylan has twice the amount Leo has plus an addition of 3 more dollars.
Therefore, the solution is 2d+3.
