Question

resuelva las siguientesecuaciones de primer grado
6-3x+9=7x
-6x-3x=8x+12
4x+x=10
8-x+3=5x

Answer 1

6 - 3x + 9 = 7x

12 = 7X + 3X

12 = 10X

12/10 = X

6/5 = X

- 6x - 3x = 8x + 12

- 9 X = 8X + 12

-12 = 8X + 9X

-12 = 17X

-12/17 = X

4x + x = 10

5X = 10

X = 10/5

X = 2

8 - x + 3 = 5x

11 - X = 5X

11 = 5X - X

11 = 4X

11/4 = X
