Question

Tentukanlah penyelesaian persamaan berikut

2. 2r + 3 = r + 7
3. 3h + 12 - 2h = 12

tolongin dijawab pake cara

Answer 1

1. 3t + 1= 2t + 4 
    3t - 2t = 4 - 1
    t = 3
2. 2r + 3 = r + 7
    2r - r = 7 -3
    r = 4
3. 3h + 12 - 2h = 12
   h = 12 - 12
   h = 0

Answer 2

1. 3t + 1 = 2t + 4
3t - 2t = 4 - 1
t = 3
2. 2r + 3 = r + 7
2r - r = 7 - 3
r = 4
3. 3h + 12 - 2h = 12
3h - 2h = 12 - 12
h = 0
