Question

1) 4[2t - (3 - t) + 5] = -(2 + 7t)

2) -[6x - (4x+8)] = 9 + (6x+3)

3) 4 (k+2) - 8k - 5 = -3k+9 - 2(k+6)

4) -7(2x+1) + 5(3x+2) = 6(2x - 4) - (12x+3)

Answer 1

1. 4[2t - (3 - t) + 5] = -(2 + 7t)

4[2t - 3 + t + 5] = -2 - 7t

4(3t + 2) = -2 -7t

12t + 8 = -2 -7t

19t = -10

t = -19/10 OR -1.9

2. -[6x - (4x+8)] = 9 + (6x+3)

-[6x - 4x -8] = 9 + 6x + 3

-6x + 4x + 8 = 9 + 6x + 3

-2x + 8 = 6x +12

-8x = 4

x = -1/2

3. 4(k+2) - 8k - 5 = -3k + 9 - 2(k+6)

4k + 8 - 8k - 5 = -3k + 9 - 2k - 12

-4k + 3 = -5k -3

k = -6

4. -7(2x+1) + 5(3x+2) = 6(2x - 4) - (12x+3)

-14x - 7 + 15x + 10 = 12x - 24 - 12x - 3

x + 3 = -27

x = -30

I have a feeling I did the first one wrong. xD

But, I'm pretty sure about the rest.

-edit-

Gah, I did do the first one wrong. I refigured, though. It's correct now.

Answer 2

1) 4[2t - (3 - t) + 5] = -(2 + 7t)

8t - 12 + 4t + 20 = -7t - 2

12t + 8 = -7t - 2

19t = -10

t= -1.9

2) -[6x - (4x+8)] = 9 + (6x+3)

-6x + 4x +8 = 6x + 9

-2x + 8 = 6x + 9

-8x = 1

x= -1/8

3) 4 (k+2) - 8k - 5 = -3k+9 - 2(k+6)

4k + 8 - 8k - 5 = -3k + 9 - 2k - 12

-4k + 3 = -5k -3

k= -6

[caught my mess up XD]

4) -7(2x+1) + 5(3x+2) = 6(2x - 4) - (12x+3)

-14x - 7 + 15x +10 = 12x - 24 -12x -3

x + 3 = -27

x= 30

:] math is fun lol

Answer 3

Assuming that I solved these correctly, you answers are below. Due to a lack of time, I only solved the last two. Sorry. Also, do not trust scarlettsixxx's answers as they are incorrect.

3.) 4 (k+2) - 8k - 5 = -3k+9 - 2(k+6)

4k + 8 - 8k - 5 = -3k + 9 -2k - 12

-4k + 3 = -5k - 3

-4k = -5k -6

k = -6

4.) -7(2x+1) + 5(3x+2) = 6(2x - 4) - (12x+3)

-14x - 7 + 15x + 10 = 12x - 24 - 12x - 3

x + 3 = -27

x = -30
