Question

Solve the following system of equations graphically.
1. 2x + 3y =2; x -2y=8
2. x -2y =2; 4x -2y = 5
3. 2x+ 3y = 4; 4x + 6y =12
4. 3x – y =5; 6x-2y=10
5. 2x+y =6; 6x +3y =18
6. 2y –x=9; 4y-2x =20
Plzzzz do the question and upload it I will mark u the brainliest ❤️. Also now spamming

Answer 1

Answer:

1. x = 4 & y = –2

2. x = 1 & y = –1/2

3. This equation has no solution.

4. This solution is in parametric form

i.e, x = x & y = –5 + 3x .

5. This solution is in parametric form

i.e, x = x & y = 6 – 2x .

6. This equation has no solution.
