2 (5 - x) = (2x - 5) - Universityku

2 (5 – x) = (2x – 5)

$» : rm{ 2(5 - x) = (2x - 5)}$

$» : rm{ 2( - x + 5) = (2x - 5)}$

$» : rm{ - 2x + 10 = 2x - 5 }$

$» : rm{ - 2x - 2x = - 5 - 10 }$

$» : rm{ - 4x = - 15}$

$» : rm{ x = frac{ - 15}{ - 4} }$

$» : rm{x = frac{15}{4} }$

Penjelasan dengan langkah-langkah:

2(5 – x) = (2x – 5)

10 – 2x = 2x – 5

-2x – 2x = -10 – 5

-4x = -15

x = -15/-4

x = 3¾
