3(-3+2y)=4(-3-y)+1 himpunan persamaan 2 variabel

Bab : Persamaan Linear Satu Variabel ( PLSV )
Kelas :VII SMP

3(-3 + 2y) = 4(-3 - y) + 1
-9 + 6y = -12 - 4y + 1
-9 + 12 - 1 = -4y - 6y
3 - 1 = -10y
2/-10 = y
1/-5 = y
-1/5 = y

semoga membantu

3(-3 + 2y) = 4(-3 -y) + 1
-9 + 6y = -12 - 4y + 1
6y + 4y = -11 + 9
10y = - 2
y = - 2/10
y = - 1/5
