X + 3 = 2x +6carilah nilai X​

Penjelasan dengan langkah-langkah:

x + 3 = 2x + 6

(x – 2x) = 3 – 6

(1x – 2x) = -3

-1x = -3

x = -3

Jawab:

x = -3

Penjelasan dengan langkah-langkah:

x + 3 = 2x + 6

x + 3 – 3 = 2x + 6 – 3

x = 2x + 3

x – 2x = 2x + 3 – 2x

-x = 3

frac{-x}{-1} = frac{3}{-1}

x = -3
