7x = 21
x = 3
1b. 2 - 4x = 3
-1 = 4x
- 1/4 = x (ini aneh, katanya x nya bil asli tpi ini ketemunya pecahan)
1c. x - 12 = 2x + 36
- 48 = x (ini aneh juga, setahuku negatif itu bil bulat)
1d. pertanyaan nggk lengkap
1. 2x - 3 = 5
2x - 3 + 3 = 5 + 3
2x = 8
x = 4
2. 2x - 6 = 9x + 8
- 14 = 7x
- 2 = x
3. 5x - 10 = 3x + 2
2x = 12
x = 6
4. 24y - 11 = 33 - 20 y
44 y = 44
y = 1
6x +x = 26 - 5
7x = 21
x = 21 : 7
x = 3
b. 2 - 4x = 3
-4x = 3 - 2
-4x = 1
x = 1 : -4
x = -0,5
