Bonjour je dois résoudre ses équations et je n'arrive pas du tous aidez-moi s'il vous plait . 4x+22=34 23m+14=7m-2 9x=3(x-8) 3(2t+5)=4(5t+7) 2(3x+4)-5(1-2x)=7(2

4x + 22 = 34
4x = 34 - 22
4x = 12
x = 12/4
x = 3

23m + 14 = 7m - 2
23m - 7m = - 2 - 14
16m = - 16
m = - 16/16
m = - 1

9x = 3(x - 8)
9x = 3x - 24
9x - 3x = - 24
6x = - 24
x = - 24/6
x = - 8

3(2t + 5) = 4(5t + 7)
6t + 15 = 20t + 28
15 - 28 = 20t - 6t
- 13 = 14t
- 13/14 = t

2(3x + 4) - 5(1 - 2x) = 7(2x - 3) + 12
6x + 8 - 5 + 10x = 14x - 21 + 12
16x + 3 = 14x - 9
16x - 14x = - 9  - 3
2x = - 12
x = - 12/2
x = - 6

4x+22=34
4x+22=34
4x=34-22
4x=12
x=12/4
x=3

23m+14=7m-2
23m-7m=-2-14
16m=-16
m=-16/16
m=-1

9x=3(x-8)
9x=3x-24
9x-3x=-24
6x=-24
x=-24/6

3(2t+5)=4(5t+7)
6t+15=20t+28
6t-20t=28-15
-14x=13
x=13/-14

2(3x+4)-5(1-2x)=7(2x-3)+12
6x+8-5+10x=14x-21+12
6x+10x-14x=12-21-8+5
10x-14x=12+5-21-8
-4x=17-29
-4x=-12
x=-12/-4
x=12/4
x=3
