Cevap :
- 2x+5 = 3x-7 → x = 12
- 7x+1 = 3x-7 → 4x=-8 → x=(-2)
- -x+4 = 5x-2 → 6x=6 → x=1
- 5x+7 = -1-3x → 8x=-8 → x=(-1)
- 2(x-3) = x-1 → 2x-6=x-1 → x=5
Adım adım açıklama:
1.
2x+5 = 3x-7
5+7 = 3x-2x
12 = x
2.
7x+1 = 3x-7
7x-3x = -1-7
4x = -8
x = -2
3.
-x+4 = 5x-2
4+2 = 5x+x
6 = 6x
x = 1
4.
5x+7 = -1-3x
5x+3x = -1-7
8x = -8
x = -1
5.
2(x-3) = x-1
2x-6 = x-1
2x-x = 6-1
x = 5
