Answer:


x=1


y=2

Explanation:

Given Equation :


6x-y=4 \\ Equation:1


3x+y=5 Equation:2

Using Elimination method add Equation:1 and 2:


6x-y+(3x+y)=4+5\\


6x-y+3x+y=9\\\\6x+3x=9


9x=9

Dividing '
9' both the sides:


x=1

Putting the value of 'x' in equation:2


3x+y=5


3(1)+y=5


3+y=5

Subtracting '3' both sides:


y=5-3


y=2

The solution of the equation is:


x=1


y=2
