Himpunan penyelesaian 4x+3y=13 x+y=4

4x + 3y = 13
x + y = 4

x + y = 4
y = 4 - x

4x + 3y = 13
4x + 3(4 - x) = 13
4x + 12 - 3x = 13
x = 13 - 12
x = 1

y = 4 - x
y = 4 - 1
y = 3

Maaf Kalau Salah

Bab Persamaan Linear
Matematika SMP Kelas VIII

x + y = 4 → 3x + 3y = 12

4x + 3y = 13
3x + 3y = 12
------------------ -
         x = 1

x + y = 4
1 + y = 4
y = 4 - 1
y = 3
