Question

1-2x = 6
3x + 2 = 5x - 3
2-4a = 3 - 5a
1+ 2x - 3 = 4x - 5 + 6
5x – 9 = 3.(x-2)
4x - 8 = -4. (2x-3) + 4

Answer 1

Respuesta:

1) x = -5/2

2) x= 5/2

3) a = 1

4) x = -3/2

5) x = 3/2

6) x = 0

Explicación paso a paso:

1) 1-2x = 6

-2x = 6-1

-2x = 5

x = -5/2

2) 3x + 2 = 5x - 3

3x - 5x = -3 - 2

-2x = -5

x = 5/2

3) 2 - 4a = 3 - 5a

-4a + 5a = 3 - 2

a = 1

4) 1 + 2x - 3 = 4x - 5 + 6

-2 + 2x - 4x = 1 + 2

2x - 4x = 1 + 2

-2x = 3

x = -3/2

5) 5x - 9 = 3 • (x - 2)

5x - 9 = 3x - 6

5x - 3x = -6 + 9

2x = 3

x = 3/2

6) 4x - 8 = -4 • (2x - 3) + 4

4x - 8 = 8x - 12 + 4

4x - 8 = 8x - 8

4x = 8x

4x - 8x = 0

-4x = 0

x = 0
