Question

Solve the simultaneous equations using Cramer’s rule.

3 − 4 = 10 ; 4 + 3 = 5​

Answer 1

Answer:

14/3, 8/4=1/2

Step-by-step explanation:

Answer 2

3x-4y=10 matrix form /[3 -4] [x] [10]

4x+3y=5 [4 3] [y] = [5]

by Cramer law

x= 10 -4 [3 -4] = 30-(-20)/9-(-6) = 50/25=2

5 3/ [4 3]

y= [3 10] [ 3 -4] = 15-40/25 = 25/25=1

[4 5] / [4 3]
