Question

Ayuda pls hagan que en la comprobación me de -40/2 porfavor es para mañana ​

Answer 1

Respuesta:

( 5-3x )-( - 4x+6 ) = ( 8x+11 )-( 3x-6 )

5-3x+4x-6 = 8x+11-3x+6

(-3+4)x+( 5-6) = ( 8-3 )x+(6+11)

x+( -1 ) = 5x+17

x-1 = 5x+17

-1-17 = 5x-x

-18 = 4x

(-18/2) = (4/2)x

- 9 = 2x

( -9/2 ) = (2/2)x

- 9/2 = x

x = - 9/2

Verificación :

( 5-3(-9/2))-(-4(-9/2)+6) = (8(-9/2)+11)-(3(-9/2)-6)

(5-(-27/2))-(-2(-9)+6) = (4(-9)+11)-(-27/2-6)

(5+27/2)-(-(-18)+6) = (-36+11)-(-39/2)

(37/2)-(18+6) = (-25)+39/2 ; 25 = 50/2

37/2-24 = -50/2+39/2 ; 24 = 48/2

37/2-48/2 = -50/2+39/2

-11/2 = -11/2

R// Por lo tanto , " x " vale - 9/2 en dicha ecuación lineal
