Q [88/100]800 + 200x = 100x =yuu bisa yuu

$» : rm{ 800 + 200x = 100}$

$» : rm{200x + 800 = 100 }$

$» : rm{200x = 100 - 800 }$

$» : rm{ 200x = - 700}$

$» : rm{ x = - frac{ 700}{200} }$

$» : rm{ x = - 3,5}$

Pembuktian

$» : rm{ 800 + 200x = 100}$

$» : rm{ 800 + 200( - 3,5) = 100}$

$» : rm{ 800 + ( - 700) = 100}$

$» : rm{800 - 700 = 100 }$

$» : rm{ 100 = 100}$

Jawaban:

800 + 200x = 100

200x = 100 – 800

200x = -700

x = -700/200

x = -3,5

800 + 200(-3,5) = 100

800 + (-700) = 100

100 = 100
