. Solve the systems of linear equations in two variables using substitution. Show the steps on how to solve by substitution. (If a system is inconsistent, then write NO solution and if a system is dependent write INFINITELY MANY solutions.)

1.{x-y = 6
y-x = 2

2. {x-y = 13
x=4y + 1

3. {x+y = 0
2x + 2y = 16

4. {x + 4y = 21
x - 2y = 0

5. { x - y = 3
4x + 3y = 5​
