To solve these simultaneous equations we first need to eliminate one variable (the x or the y). For this we will need the coefficients (numbers in front of the variables) to be equal or opposite on one varia...

Rearrange both equations into the form ax + by = c. 3x+3y = 12.5 6x +2y = 5. 2) Make either x or y have the same coefficient in each equation. In this case we use x, to do this we multiply the first equation...

Une réponse potentielle: Certainement en ville, je suis sans doute. Personellement, la tranquilité à la campagne ne m'amuse jamais. J'aime bien le fait qu'en ville, c'est très animé et il y a beaucoup à fair...

x^2 - 7x - 18

X coordinates = (-3+1)/2 = (-2)/2 = - 1Y coordinates = (-3+3)/2 = (0) /2 = 0 Coordinates of the midpoint = (x,y) = (-1,0) If they were struggling to visualise it/to avoid simple mistakes, I would suggest qui...
