Question

3x + 2y = 5 4x - 3y = 18 using inverse matrix

Answer 1

Answer:

4x + 3y = 18 and 3x -2y = 5

Sol: x = 3 & y = 2

Step-by-step explanation:

4x + 3y = 18  - eq 1

3x -2y = 5     - eq 2

Multiplying Eq 1 by 2 & eq 2 by 3

8x + 6y = 36

9x - 6y = 15

Elimination y by Adding both

17x = 51

x = 3

now substituting value of x into Eq 1

4*3 + 3y = 18

=> 3y = 6

=> y = 2
