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.

X^3 - y^3 = 218 where x and y are positive integers. Find x+y
finlep [7]

The value of x + y is 12

<h3>How to solve for x + y?</h3>

The equation is given as:

x^3 - y^3 = 218

Make x^3 the subject

x^3 = 218 + y^3

The next cubic expression greater than 218 is 343.

So, we assume

x^3 = 343

This gives

x = 7

Substitute x^3 = 343 in x^3 = 218 + y^3

343 = 218 + y^3

Evaluate the like terms

y^3 = 125

This gives

y = 5

So, we have:

x + y = 7 + 5

Evaluate

x + y = 12

Hence, the value of x + y is 12
