Question

Tolong Dijawab yaa Tentang Aljabar :) Terima kasih sebelumnya :)
1. Untuk persamaan 7x + 5 = 9x + 11, tentukan nilai x + 4 !
2. 2 (q + 3 ) + 3(3q - 4 ) = 9
3. 3 (1 - q ) + 4 ( q - 5 ) = -5
4. 4 (x - 3 ) - 2 (x - 3 ) = 8
5. 4x + 3(x - 2 ) - (5 - 4x ) = 0
6. 3 (2x - 3 )- 2 (x + 1 ) = x - 3
7. 8y - 5 (2y - 3 ) = 4(y - 3) + 18
8. 5 (2y + 4 ) - (10y - 16) = 6 - 4y

Tolong Dijawab yaa semuanya kalo bisa ;D
Pake jalan :)

Answer 1

7x + 5 = 9x + 11
7x - 9x = 11 -5
-2x = 6
x = -3
-3 + 4 = 1

2q + 6 + 3q - 4 = 9
2q + 3q = 9 - 6 + 4
5q = 7
q = 7/5
