Question

Solve the following simultaneous equations using cross multiplication method
only:-
3x + 2 y = 10
4 x − 3 y − 10 = 0

Answer 1

Answer:

x=10/17 y=70/17

Step-by-step explanation:

a1=3 b1=2 c1=-10

a2=4 b2=-3 c2=-10

x/b1c2-b2c1 = y/c1a2-c2a1 = -1/a1b2-a2b1

Now you can put the values and you will get the given answer
