Question

Penyelesaian linear 1/4(x-10) = 2/3(x-5)

Answer 1

1/4 x - 10/4 = 2/3 x - 10/3
1/4 x - 2/3 x = 10/4 - 10/3
3/12 x - 8/12x = 30/12 - 40/12
-5/12 x = -10/12
 x =  -10/12 : -5/12
    = -10/12 x -12/5
    = 10/5 = 2

Answer 2

1/4 (x-10) = 2/3 (x-5)
Dikali 12
jadinya 3 (x-10) = 8 (x-5)
3 x - 30 = 8 x - 40
-30 + 40 = 8 x - 3 x
10 = 5 x
x = 10 dibagi 5
x = 2
