5x – 15 = 5 × x – 5 × 3 = 5( x 3) factorisation 2(y 9) = 2y (9) = 2y (2) × (9) = 2y – 18 développement 3x 5 x = (3 5) x = 8 x factorisation Vérification pour vérifier que l'on n'a pas fait d'erreur on peut choisir un nombre qui remplacera l'inconnue dans les premières et dernières expressions On doit alors trouver le même résultat Exemples si x=5Algebra Solve by Substitution xy=5 , xy=1 x y = 5 x y = 5 , x − y = 1 x y = 1 Subtract y y from both sides of the equation x = 5− y x = 5 y x−y = 1 x y = 1 Replace all occurrences of x x with 5−y 5 y in each equation Tap for more steps Replace all occurrences of x x in x − y = 1 x y = 1 with 5 − y 5 y

So % of 60 is 12 Double check your answer with the If you have a sum, then we start with positive and alternate signs The reason for this is that all but one of our pairs must cancel out Let's look at your example x 5 y 5 = (xy) (x 4 y 0 x 3 y 1 x 2 y 2 x 1 y 3 x 0 y 4 ) Since anything to the 0 power equals 1 and anything to the first power is itself, then we havePointSlope Formula y − y 1 = m (x − x 1 ) where m is the slope and (x 1 , y 1 ) is the given point Now substituting the values y − 0 = 4 5 (x − (− 4)) ⇒ y = 4 5 (x 4) ⇒ 4 y = 5 (x 4) ⇒ 4 y = 5 x 2 0 ⇒ 4 y − 2 0 = 5 x Hence, the equation of the line is 4 y − 2 0 = 5 x Was this answer helpful?
