Answer:
1. x = 2
2. x = 4
3. x = 5
4. x = -2k
5. x = 1
Answer:
1. 5(6x+2)-2(1-6x)=42x+8
30x + 10 - 2 + 12x = 42x + 8
42x + 8 = 42x + 8
2. -5(6-3x)-2(x-1) =-28+13x
-30 + 15x - 2x + 2 = -28 + 13x
13x - 28 = 13x - 28
3. -2(x-8)-7(7-2x)=12x-65
-2x + 16 - 49 + 14x = 12x - 65
12x - 33 = 12x - 65
4. 8(1-4x)-5(-8k-2x)=12x-65
8 - 32x + 40k + 10x = 12x - 65
-22x + 40k + 8 = 12x - 65
-34x + 40k = -73
x = (40/34)k + (73/34)
5. 2(x-8)-2(-5x-1)=12x-14
2x - 16 + 10x + 2 = 12x - 14
12x - 14 = 12x - 14
