Me resuelven estas ecuaciones?

Me resuelven estas ecuaciones? Porfavor 2x = 5 + x 7 = 4x - 1 x = 2x - 3 3x = 10 - x 3 = 2x - 5 x = 5x - 8 x = 6 - x 5 = 2x + 3 x = 3x - 12 5x = 2 + x 2 = 4x - 1 x = 4x - 1.

2x = 5 + x x = 5

7 = 4x - 1 7 + 1 = 4x 8 / 4 = x x = 2

x = 2x - 3 x - 2x = - 3 - x = - 3 se simplifican los signos x = 3

3x = 10 - x 3x - x = 10 2x = 10 x = 10 / 2 x = 5

3 = 2x - 5 3 + 5 = 2x 8 / 2 = x X = 2

x = 5x - 8 8 = 5x - x 8 = 4x X = 2

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

5 = 2x + 3 5 - 3 = 2x 2 / 2 = x

x = 3x - 12 12 = 3x + x 12 / 4 = x x = 3

5x = 2 + x 5x - x = 2 x = 2 / 4 x = 1 / 2

2 = 4x - 1 2 + 1 = 4x 3 / 4 = x

x = 4x - 1 1 = 4x - x x = 1 / 3.

A) 2x = 5 + x

2x - x = 5

x = 5

b) 7 = 4x - 1

7 + 1 = 4x

8 = 4x

8 / 4 = x

x = 2

c) x = 2x - 3

3 = 2x - x

3 = x

x = 3

d) 3x = 10 - x

3x + x = 10

4x = 10

x = 10 / 4

e) 3 = 2x - 5

3 + 5 = 2x

8 = 2x

8 / 2 = x

x = 8 / 2

f) x = 5x - 8

8 = 5x - x

8 = 4x

x = 8 / 4

x = 2

g) x = 6 - x

x + x = 6

2x = 6

x = 6 / 2

x = 3

h) 5 = 2x + 3

5 - 3 = 2x

2 = 2x

x = 2 / 2

x = 1

i) x = 3x - 12

12 = 3x - x

12 = 2x

12 / 2 = x

x = 6

j) 5x = 2 + x

5x - x = 2

4x = 2

4 / 2 = x

x = 2

k) 2 = 4x - 1

2 + 1 = 4x

3 = 4x

x = 3 / 4

l) x = 4x - 1

1 = 4x - x

1 = 3x

x = 1 / 3.
