Answer:
The answer is G
Step-by-step explanation:
So what I did was I went on a website that it wont let me name and typed in each equation and then the ordered pair and checked to see if (8,-1) was a solution and it was for G.
Les trois nombres sont 5, 6 et 7.
Soit x le premier nombre.
x + 1 sera le second et x + 2 sera le troisième.
On pose l'équation :
2x + 3(x + 1) = 4(x + 2)
2x + 3x + 3 = 4x + 8
5x - 4x = 8 - 3
x = 5
x = 4/5
I hope this helps!
