Tentukan penyelesaian dari persamaan berikut!
1. 4(x + 6) = 3(x + 2)
2.3(2x + 7) = 5(x - 4)
3.2(5x - 6) = 3(3x - 7)
4.5(y - 4) + 2y = 6(y -3)
5.7(2y + 3) - 5y = 4(2y + 7)
Please jawab kak
1. 4(x + 6) = 3(x + 2)

3.2(5x - 6) = 3(3x - 7)
4.5(y - 4) + 2y = 6(y -3)
5.7(2y + 3) - 5y = 4(2y + 7)
Please jawab kak
4x - 3x = 6 - 24
x = -18
2. 6x + 21 = 5x - 20
6x - 5x = -20 - 21
x = -41
3. 10x - 12 = 9x - 21
10x - 9x = -21 + 12
x = -9
4. 5y - 20 + 2y = 6y - 18
5y + 2y - 6y = -18 + 20
y = 2
5. 14y + 21 - 5y = 8y + 28
14y - 5y - 8y = 28 - 21
y = 7
maaf jika salah. ..
