Matematika SMP Kelas VII

(4x + 3)/3 + (4/5) (1 - x) = (6x + 5)/3
**dikali 15**

5 (4x + 3) + 12 (1 - x) = 5 (6x + 5)
20x + 15 + 12 - 12x = 30x + 25
27 - 25 = 30x - 8x
22x = 2
x = 2/22
x = 1/11

4x+3/ 3 + 4/5 (1-x) = 6x+5/ 3
-------------------------------------- × 15

5(4x+3) + 12(1-x) = 5(6x+5)
20x +15 + 12-12x = 30x +25
8x + 27= 30x + 25
8x - 30x = 25 - 27
-22x = -2
x = -2/-22
x = 2/22
