Question

Assalamualaikum aku mau nanya soalnya aku gak ngerti bangett sama soal yang ini. bantu aku ya :)

Answer 1

B>>> x/3 - y/2 = 7/6
2x/6 - 3y/6 = 7/6
2x-3y / 6 = 7/6
2x - 3y = 7

x/2 + y/4 = - 5/4
2x/4 + y/4 = - 5/4
2x + y / 4 = - 5/4
2x + y = -5

C>>>
4y/xy - 3x/xy = 11
4y - 3x / xy = 11
4y - 3x = 11xy

4y/xy - 4x/xy = 2
4y - 4x / xy = 2
4y - 4x = 2xy

D>> 
x + 1 / 4 - 2y + 4 / 4 = 6
x - 2y + 5 = 24
x - 2y = 19

4x - 4 / 6 + 3y - 1 / 6 = 7
4x + 3y - 5 = 42
4x + 3y = 47
