2-(3-4x)=2(3-4x)
2-3+4x = 6 - 8x
4x + 8x = 6 + 1
12x = 7
x = 7/12
7(2x-5)-3x = 4 + (8x +1)
14x - 35 - 3x = 4 + 8x + 1
11x - 8x = 5 + 35
3x = 40
x = 40/3
4 - (3x -5) = -4(3x-2)
4-3x+5=-12x + 8
-3x + 12x = 8 - 4 - 5
9x = -1
x = -1/9
J'ai encore besoins de votre aide,s'il vous plaît!
quelques équations:
2-(3-4x)= 2(3-4x)
7(2x-5)-3x = 4+ (8x+1)
4-(3x-5)= - 4(3x-2)
2-(3-4x)=2(3-4x)
2-3+4x = 6 - 8x
4x + 8x = 6 + 1
12x = 7
x = 7/12
7(2x-5)-3x = 4 + (8x +1)
14x - 35 - 3x = 4 + 8x + 1
11x - 8x = 5 + 35
3x = 40
x = 40/3
4 - (3x -5) = -4(3x-2)
4-3x+5=-12x + 8
-3x + 12x = 8 - 4 - 5
9x = -1
x = -1/9
