Math Review:How do you solve questions by elimination, substitution and how do you simplify fractions?

Example 1: Consider these equations:

2x - 5y = 1

3x + 5y = 14
(Elimination)

Use the substitution method to solve the linear system.
5x + 3y = 26
x - 3y = 4

Ex. 2 3/4 + 3 1/2 How do you simplify these?
Thanks!!!
Can anyone also explain their answer?
