Bonjour, j’aurais besoin de votre aide se sont des équations à résoudre
À rendre pour aujourd’hui

2x + 5 =5x-4
3x-8=8x+2
2x+1=x-4
4x-5=2x+2

3x+4=8x-21
-2x+1=7x-80
2x-3=5x+3
5x-3=3x-5

2(x+3)=4(x-1)
5(1-x)=3(2x+1)
-(x-2)=2(2x+1)
3x+1=3(2-x)

3(x+1)=2(3x-5)
-(5-2x)=3x
4(2x+4)-3(5-x)=2(x+1)

2(x-2)=3x+3(2x+1)
-(x+2)=3(2x+1)
2(x-1)-3(2x-4)=3x+5

3(2-3x)+4(x+2)=4x+2(x-2)
5x+2-3(2-4x)=2(3x+4)
-3(x+2)+4(5-x)=2x+5

3x+1=x-3
3-4x=10x+7
2(x+1)-4=4x+1
3-2(2x+1)=5(2-x)

3x+2=6
14x+1=8
10x+14=19
9x+7=28

3x+2=x+5
4x+7=x+12
