Himpunan penyelesaian 1. (2y-3)/2 + (5y+4)/4 = 4 2. (2x-3)/2 = 4 + (5x+6)/4

1.) (2y - 3)/2 + (5y - 4)/4 = 4
<=> (2y - 3)/2 + 4/(5y-4) = 4
<=> 8y - 12 + 10y - 8 = 4
<=> 8y + 10y = (12 + 8)/4
<=> 18y = 5
<=> y = 18/5
<=> y = 3,33

2.) (2x - 3)/2 = 4 + (5x + 6)/4
<=> (2x - 3)/2 - 4/(5x + 6) = 4
<=> 8x - 12 + 10x + 12 = 4
<=> 8x + 10x - 12 + 12 = 4
<=> 18x = 4
<=> x = 18/4
<=> x = 4,2

Maaf kalo salah:)
