Algebraaaa!!! HELP!! pleaseee!?

Question

1. -10t - 4 = 30

Solve each equation and justify each step.

1. 8 + c/-4 = -6

2. 7 - 3k = -14

3. 2p - 6 = 14

4. -y/2 + 14 = -1

Answer 1

1. -10t - 4 = 30

-10t = 34 {adding four to both sides}

t = -3.4 {dividing both sides by -10}

1. 8 + c/-4 = -6

-32 + c = 24 {multiply both sides by -4}

c = 56 {add 32 to both sides}

2. 7 - 3k = -14

-3k = -21 {take 7 from both sides}

k = 7 {divide both sides by -3}

3. 2p - 6 = 14

2p = 20 {add 6 to both sides}

p = 10 {divide both sides by 2}

4. -y/2 + 14 = -1

-y/2 = -15 {subtract 14 from both sides}

y = 30 {multiply both sides by -2}

Answer 2

1.

-10t - 4 = 30

-10t = 30 + 4

-10t = 34

t = 34/-10

t = -17/5

2.

8 + c/-4 = -6

c/-4 = -6 - 8

c/4 = -14

c = -14 x 4

c = -56

3.

2p - 6 = 14

2p = 14 = 6

2p = 20

p = 20/2

p = 10

4.

-y/2 + 14 = -1

-y/2 = -1 - 14

-y/2 = -15

-y = -15 x 2

-y = -30

y = 30

Answer 3

1. c/-4 = -14 ???

2.  -3k = -21

     k = 7

3. 2p = 20

     p = 10

4. -y/2 = -15 ???

    

Answer 4

8 + c/-4 = -6    add -8 to both sides

c/-4 = -14      multiply by -4

c= + 56

7 - 3k = -14     subtract 7

-3k = -21     multiply by -1

3k =21     divide by 3

k=7

2p-6=14   add 6

2p = 20    divide by 2

p = 10

-y/2 +14 =-1            subtract 14

-y/2  = -15

-y = -30

y = 30

Answer 5

1.   t=-3.4   or    -17/5

1. -4(8 + c/-4 = -6)

        -32+c=24

         -56=c

2.   7-3k=-14

       -3k=-21

          k=7

3.   2p-6=14

       2p=20

         p=10

4.   2(-y/2+12=-1)

         -y+24=-2

          -y=-26

            y = 26
