Question

Sederhanakan bentuk-bentuk al jabar berikut beserta caranya :
1. 12p + 4(2x - 3) =
2. 10a - (2a - 5)=
3. 5(x -2y) -3 (2x-y) =
4. -3 (x -4y) + 4(5x -3y) =

Answer 1

1. 12p + 4(2x - 3) = 12p + 8x - 12 = 4(3p + 2x - 3)

2. 10a - (2a - 5) = 10a - 2a + 5 = 8a + 5

3. 5(x - 2y) - 3(2x - y) = 5x - 10y - 6x + 3y = -x - 7y

4. -3 (x - 4y) + 4(5x - 3y) = -3x + 12y + 20x - 12y = 17x
