Answer:

Explanation:

2) the given system of equations is expressed as

y = 2x + 5 - - - - - - - - - - - - - - 1

y - 2x = 1- - - - - - - - - - - - - - 2

Substituting equation 1 into equation 2, it becomes

2x + 5 - 2x = 1

2x - 2x = 1 - 5

0 = - 4

The result of plotting both equations on a graph would be 2 parallel lines that will never intersect. Therefore, there are no solutions

3) the given system of equations is expressed as

3x - 2y = 9 - - - - - - - - - - - - - 1

- 6x + 4y = 1- - - - - - - - - - - - - 2

Multiplying equation 1 by 6 and equation 2 by 3, it becomes

18x - 12y = 54

- 18x + 12y = 3

Adding both equations, it becomes

0 + 0 = 57

Therefore, there are no solutions.
