Answer:

x=1, y=1. (1, 1).

Step-by-step explanation:

4x+6y=10

6x=9y-3

-----------------

4x+6y=10

9y-6x=3

-----------------

4x+6y=10

-6x+9y=3

---------------

simplify -6x+9y=3 into -2x+3y=1

------------------------

4x+6y=10

-2x+3y=1

---------------

4x+6y=10

2(-2x+3y)=2(1)

-----------------------

4x+6y=10

-4x+6y=2

---------------

12y=12

y=12/12

y=1

4x+6(1)=10

4x+6=10

4x=10-6

4x=4

x=4/4=1
