Question

5x+8=-2
4-2x=8
10=2x+6
-16=2-9x

Answer 1

son ecuaciones lineales de una variable, se pueden resolver:
5x+8=-2
5x = -2 - 8
5x = -10
x = -2

4 - 2x = 8
2x = 4 - 8 = -4
x = -2

10 = 2x + 6
10 - 6 = 2x
2x = 4
x = 2

-16 = 2 - 9x
9x = 16 + 2
9x = 18
x = 2

Answer 2

1) 4 - 2x = 8
       4 - 8 = 2x
        -4/2 = x
           x= -2

2) 10 = 2x + 6
     10 - 6 = 2x
      4 = 2x
     x = 4/2
     x = 2

3) -16 = 2 - 9x
      9x = 2 + 16
       9x = 18
        x = 18/9
        x = 2
