5x-7per2 - 2x+7per3 = 3x-14

5x-7 / 2 - 2x+7 / 3 = 3x-14
3(5x-7) -2(2x+7) / 6 = 3x-14
15x -21 -4X -14 = 6(3X-14)
11X -35 =18X -84
11x - 18x = -84 + 35
-7x = -49
x = -49 / -7
x = 7

jawab

(5x -7)/2 -(2x +7)/3 = 3x  - 14 ||kali 6
3(5x -7) - 2(2x +7) =6(3x -14)
15x - 21 - 4x - 14 = 18 x - 84
15x - 4x -18x = -84 +21 +14
-7x = -49
x = -49/-7
x = 7
