Answer:

1) x = -4

2) m = -8

3) x= 5

4) x = -3

5) y = 1

6) y = -4

7) n = -3

8) y = 1

9) x = \frac{8}{3}

10) y = 4

11) a = -\frac{14}{3}

12) y = 2

Step-by-step explanation:

1) 5x + 32 = 8 -x

5x + 32 +x  = 8 -x +x

6x + 32 = 8

6x +32 - 32 = 8 -32

6x = -24

\frac{6x}{6} =\frac{-24}{6}

x = -4

2) m - 12 = 3m +4

m - 12 -3m = 3m -3m +4

-2m -12 = 4

-2m -12 +12 = 4 + 12

-2m = 16

\frac{-2m}{-2}= \frac{16}{-2}

m = -8

3) 2x + 2 = 3x -3

2x +2 -3x = 3x -3x -3

-x +2 = -3

-x +2 - 2 = -3 -2

- x = -5

\frac{-x}{-1}= \frac{-5}{-1}

x = 5

4) 15x + 25 = 4x -8

15x + 25 -4x = 4x - 4x -8

11x + 25 = -8

11x +25 - 25 = -8 -25

11x = -33

\frac{11x}{11}= \frac{-33}{11}

x = - 3

5) 8y-3=10y +5

8y -3 - 10y = 10y - 10y +5

-2y - 3 =5

-2y - 3 +3 = 5 +3

-2y = 8

\frac{-2y}{-2}= \frac{8}{-2}

y = -4

6) 2y - 4 = 12 -14y

2y - 4 +14y = 12 - 14y + 14y

16y - 4 = 12

16y - 4 +4 = 12 +4

16y = 16

\frac{16y}{16} =\frac{16}{16}

y =1

7) 15 n + 25 = 2n - 14

15n -+25 -2n = 2n -2n -14

13n + 25 = -14

13n +25 - 25 = -14 -25

13n=-39

\frac{13n}{13} =\frac{-39}{13}

n = -3

8) 4y +2 = 18 -12y

4y +2 +12y = 18 -12y +12y

16y + 2 = 18

16y +2 -2 = 18 -2

16y = 16

\frac{16y}{16}= \frac{16}{16}

y =1

9) 6x -2 = 3x + 6

6x - 2 -3x = 3x -3x +6

3x -2 =6

3x -2 +2 = 6 +2

3x = 8

\frac{3x}{3} =\frac{8}{3}

x = \frac{8}{3}

10) 13y - 8 = 7y +16

13y -8 -7y = 7y -7y +16

6y -8 = 16

6y - 8 +8 = 16 +8

6y = 24

\frac{6y}{6}= \frac{24}{6}

y = 4

11) 9a - 22 = 12a - 8

9a - 22 - 12a = 12a -12a -8

-3a - 22 = -8

-3a - 22 +22 = -8 +22

-3a = 14

\frac{-3a}{-3} =\frac{14}{-3}

a = -\frac{14}{3}

12) 4y - 4 = 16 -2y

4y +4 +2y = 16 -2y +2y

6y + 4 = 16

6y +4 -4 = 16 -4

6y = 12

\frac{6y}{6} =\frac{12}{6}

y = 2
