The Deep Dive
Pour résoudre l'expression \( (4x - y) - (5x - 3y) \), commençons par substituer les valeurs de \( x \) et \( y \) données. Cela donne : \( 4(-6) - 4 - (5(-6) - 3(4)) \). Calculons chaque partie : \( 4(-6) = -24 \), \( -(-6) = +6 \), \( 5(-6) = -30 \), \( -3(4) = -12 \) donc \( -30 - (-12) = -30 + 12 = -18 \). Maintenant, nous avons : \( (-24 - 4) - (-18) = -28 + 18 = -10 \). Ainsi, la valeur de l'expression est \( -10 \).
