D can mean anything, it's only substituting a number that you have to find out. That's how you do basic algebra
If your in English Class it Means that you should be in your Algebra Class.
In algebra, 8n means to multiply n and 8. (8xN)
algebra involves equations with numbers a variables and your goal is to solve for the variable
I think you mean Algebra 1 & 2 If you did, Algebra 1 is the basic stuff. Algebra 2, you get more complex, but it's still a basic idea.
This is easy. Make two equations, and represent the sandwiches with s and the drink with d. you get: 2s+d=10 s+2d=8 After simplifying and taking away a variable, you figure out that each sandwich costs 4 dollars and each drink costs 2 dollars. (Heres the step by step algebra) 2s +dy = 10 s + 2d = 8 2s + d = 10 2s + 4d = 16 3d = 6 d = 2 2s + d = 10 2s + 2 = 10 2s = 8 s = 4 So, Sandwich = £4 Drink = £2
