Answer:
5x-6y +30=0:
4y+5x=20
Step-by-step explanation:
Solving by elimination method
5x-6y +30=0
5x-6y+30=0 -----1
4y+5x-20=0 -----2
Equating 1 and 2, we get
5x-6y+30=4y+5x-20
=> -6y +30= 4y-20
=> -6y-4y=-20-30
=> -10y =-50
=> 10y=50
=> y= 5
Substituting value of y as 5 in 1, we get
5x-6(5)+30=0
5x-30+30=0
5x=0
=>x=0
So answer is x=0 and y=5
Hope it helps
