Answer:
x=4,y=9
Step-by-step explanation:
We want to solve the equation:
simultaneously.
Multiply the top equation by 3 and the bottom equation by 2 to get:
6y-15x=-6
6y+4x=70
Subtract the top equation from the bottom equation.
We substitute x=4 into 2y-5x=-2 to get:
Therefore the solution to the system is
(4,9)
For number 9. its 34 × 65 = 65 × 34.. So that means its communicative property
