Question

alquien me ayuda a hacer esta ecuaciones que no se como hacerla a) 7x=4x-6 B)-2X=9-X C)-6X=24+2X d)10=15-5x e)x-8=4-x f)3x-10=18-x g)7x+8=3x-4

Answer 1

7x = 4x - 6

7x - 4x = - 6

3x = - 6

x = -6/3

x = - 2
--------------------

- 2x = 9 - x

- 2x + x = 9

- x = 9

x = - 9
-------------------------
- 6x = 24 + 2x

- 6x - 2x = 24

- 8x = 24

x = 24/-8

x = - 3 
--------------------------
10 = 15 - 5x

5x = 15 - 10

5x = 5

x = 5/5

x = 1
---------------------------

x - 8 = 4 - x

x + x = 4 + 8

2x = 12

x = 12/2

x = 6
-----------------------------

3x - 10 = 18 - x

3x + x = 18 + 10

4x = 28

x = 28/4

x = 7
---------------------------

7x + 8 = 3x - 4

7x - 3x = - 4 - 8

4x = - 12

x = -12/4

x = - 3
