[tex] \frac{2}{5} x - \frac{1}{2} = 5x + 1[/tex]
hehehe tolonggg yaa
Penjelasan dengan langkah-langkah:
[tex] \frac{2}{5} x - \frac{1}{2} = 5x + 1[/tex]
[tex] \frac{4x - 5}{10} = 5x + 1[/tex]
[tex]4x - 5 = 10.(5x + 1)[/tex]
[tex]4x - 5 = 50x + 10[/tex]
[tex]4x - 50x = 10 + 5[/tex]
[tex] - 46x = 15[/tex]
[tex]x = - \frac{15}{46} [/tex]
2/5x - 1/2 = 5x + 1 [ × 10 ]
4x - 5 = 50x + 10
4x - 50x = 10 + 5
-46x = 15
x = -15/46
