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
D can mean anything, it's only substituting a number that you have to find out. That's how you do basic algebra
If you mean: 4(2s-1) = 7s+12 then the value of s works out as 16
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
