Question

Solve the follwing simultaneous equation using cramer's rule 3x-4y=10, 4x+3y=5​

Answer 1

Answer:

Step-by-step explanation:

D= (3x3)-(4x-4)

 =25

D for x = (-4x-5)-(-10x3)

           = 50

D for y = (-10x4)-(-5x3)

           = 25

Therefore  x= D for x/D

                    = 50/25

                 x = 2

                 

                  y= D for y/D

                    = 25/25

                  y = 1
