1. Jawaban MathSolver74
1. 3(3x - 4) = - 6
9x - 12 = - 6
9x = 6
x = 2/3
2. - 5(2 - x) = 10
- 10 + 5x = 10
5x = 20
x = 4
3. 3x + (x + 5) = 9
4x = 4
x = 1 -
2. Jawaban whyandi
1. 9x - 12 = -6
9x = -6 + 12
9x = 6
x = 6
9
x = 2/3
2. -10 +5x = 10
5x = 10+10
5x = 20
x = 20
5
x = 4
3. 3x + x + 5 = 9
4x = 9 - 4
4x = 4
x = 4/4
x = 1
