Explicación paso a paso:

n )

7 = 5 + 2x

7 - 5 = 2x

2 = 2x

x = 2 / 2

x = 1

o )

8 = 2 + 2x

8 - 2 = 2x

6 = 2x

x = 6 / 2

x = 3

p )

10 = 4 + 3x

10 - 4 = 3x

6 = 3x

x = 6 / 3

x = 2

q )

7 = 6 + 2x

7 - 6 = 2x

1 = 2x

x = 1 / 2

x = 0.5

r )

6 + x = 3 + 2x

6 - 3 = 2x - x

3 = x

x = 3

s )

4 + 2x = 3 + 3x

4 - 3 = 3x - 2x

1 = x

x = 1

t )

x + 6 = 3x

6 = 3x - x

6 = 2x

x = 6 / 2

x = 3

v )

x + 8 = 3x

8 = 3x - x

8 = 2x

x = 8 / 2

x = 4

w )

x + 6 = 4 + 3x

6 - 4 = 3x - x

2 = 2x

x = 2 / 2

x = 1

x )

x + 8 = 5 + 4x

8 - 5 = 4x - x

3 = 3x

x = 3 / 3

x = 1

y )

x + 16 = 13 + 4x

16 - 13 = 4x - x

3 = 3x

x = 3 / 3

x = 1
