x+y=43

4x=2y+4

In first equation subtract 'y' from both sides:

x=43-y

In second equation substitute 'x' from first equation:

4(43-y)=2y+4

Simplify by dividing by 2,

2(43-y)=y+2

Open parantheses,

86-2y=y+2

Add '2y' to both sides,

86=3y+2

Subtract 2 from both sides,

84=3y

Divide by 3,

y=28

Then,

x=43-y=43-28=15
