a) 4x+5-(3x+6)=2(2+x)-4 b) 4-5(3-x)=-x-(3-2x) c) 3(3-x)+2=8-2(x-1) proszę o rozwiązanie tego . daję NAJ !!
a) 4x+5-(3x+6)=2(2+x)-4 =
4x+5-3x-6 = 4+2x-4
x -1 = 2x
x = -1
b) 4-5(3-x)=-x-(3-2x)
4 - 15 + 5x = -x - 3 + 2x
5x - 11 = - 3 + x
4x - 8 = 0
x = 2
c) 3(3-x)+2=8-2(x-1)
9 - 3x + 2 = 8 - 2x + 2
11 - 3x = 10 - 2x
11 = 10 + x
x = 1
-x = 1
4-15+5x=-x-3+2x
-11+5x =x -3
4x =8 /:4
x=2c) 3(3-x)+2=8-2(x-1)
9 - 3x +2 = 8-2x+2
-3x +11 = 10-2x
- x =-1
x=1
