Question

4 (2-3x)=-2x-27 la comprobacion porfavor

Answer 1

4 (2-3x)=-2x-27 la comprobación por favor

4 (2 - 3x) = - 2x - 27
8 - 12x = - 2x - 27
- 12x + 2x = - 27 - 8
- 10x = - 35
10x = 35
x = 35/10
x = 7/2

Rpt. El valor de x es 7/2


COMPROBAMOS LA SOLUCIÓN.
4 (2 - 3x) = - 2x - 27
4 (2 - 3 * 7/2) = - 2 (7/2) - 27
4 (2 - 21/2) = - 14/2 - 27
8 - 84/2 = - 7 - 27
8 - 42 = - 34
- 34 = - 34

LISTO°

Answer 2

4 (2-3x)=-2x-27
8-12X=-2x-27
-12x+2x=-27-8
-10x=-35
x=-35/-10
x=7/2
COMPROBACIÓN:
4 (2-3x)=-2x-27
4(2-3·7/2)=-2·7/2-27
4(2-21/2)=-14/2-27
4(-17/2)=-7-27
-68/2=-34
-34=-34
