Jawab:

x = 2/13

Penjelasan dengan langkah-langkah:

|5c+2|+8c = 4

Penjelasan:

-4 = 5c+2+8c = 4 (menyamakan nilai c)

-4 = 13c+2 = 4 (sederhanakan nilai 2)

-4-2 = 13c+2-2 = 4-2

-6 = 13c = 2 (dikedua ruas sama-sama dibagi 13)

-6/13 = c = 2/13

x = -6/13 atau x = 2/13

Pembuktian:

c = -6/13

|5c+2|+8c = 4

(5(-6/13))+8(-6/13) = 4

(-30/13+26/13)+(-48/13) = 4

(-4/13)-48/13 = 4

-4/13-48/13 = 4

-52/13 = 4

-4 = 4 (Tidak Terbukti)

c = 2/13

|5c+2|+8c = 4

(5(2/13)+2))+8(2/13) = 4

(10/13+26/13)+16/13 = 4

(36/13)+16/13 = 4

52/13 = 4

4 = 4 (Terbukti)

HP (Himpunan Penyelesaian) = {4}

Semoga Membantu ^^
