1. 4(11x-2) + 5(3x+4)
2. 2+4(x+3) - (3x+2)

jawaban :
1.  (44x ₋ 8) + (15x + 20) ==> 44x - 8 + 15x + 20 ==>  59x + 12
2. (2 + 4x + 12)  - 3x - 2 ==> 2 + 4x +12  - 3x - 2 ==> x + 12
1. (44x - 8) + (15X + 20) = 59x + 12
2. (2 + 4x + 12) - 3x - 2 = 2 + 4x + 12 - 3x -2 = x + 12

1) (44x - 8) + (15x + 20) = 59x + 12
2) 2 + (4x + 12) - (3x +2 ) = 2 + (x + 10) = x + 12
