Solution

The given set of equations are,
2x=4y+6.....(i)
and 2(2y+3)=3x5.......(ii)

from (i)
2x=4y+6
2x+4y=6......(iii)

And,from (ii)
2(2y+3)=3x5
4y+6=3x5
3x4y=11.......(iv)

adding (iii) and (iv)
5x=5
x=1

from (iii)
2×1+4y=6
2+4y=6
4y=8
y=2

Therefore, the solution to the given system of the equations is (1,2).
