Question

Respuesta de esta ecuacion 15x+(-6x+5)-2-(-x+3)=-(7x+23)-x+(3-2x)

Answer 1

Hola Laura!

15x + (- 6x + 5) - 2 - (- x + 3) = - (7x + 23) - x + (3 - 2x)
15x - 6x + 5 - 2 + x - 3 = - 7x - 23 - x + 3 - 2x
15x - 6x + x + 5 - 2 - 3 = - 7x - x - 2x - 23 + 3
15x + x - 6x + 5 - 2 - 3 = - 7x - x - 2x - 23 + 3
16x - 6x + 5 - 5 = - 10x - 20
10x = - 10x - 20
10x + 10x = - 20
20x = - 20
x = - 20/20
x = - 1

Rpt.

x = - 1
