vamos a resolver ese problema:
a) 5 + x = 0
x = -5
b) -17 + x = 0
x = 17
c) 30 + x = 0
x = -30
d) x + (-27) = 0
x - 27 = 0
x = 27
e) x + 35 = 0
x = -35
f) -25 + x = 0
x = 25
g) x + ( -30) = 0
x - 30 = 0
x = 30
Pregunta número 2:
a) 7x - 15 = 20
7x = 35
x = 5
b) -5x - 8 = 12
-5x = 20
x = 20/-5
x = -4
c) 4x - 10 = 26
4x = 36
x = 9
d) -6x - 18 = 10
-6x = 28
x = 28/-6
x = -4.6
Pregunta número 3:
a) 7x-35-x=3
6x-35=3
6x=38
x=38/6
simplificando 19/3
b) -3(2x - 5) - 5x = 3x
-6x + 15 -5x = 3x
-11x + 15 = 3x
15 = 14x
15/14= x
c) 7(x-2)-6x+1= 3-4x
7x-14 -6x+1= 3-4x
7x - 6x + 4x = 3 + 14 -1
5x = 16
x = 16/5
d) 4x + 2 (2x - 5) = (x - 3) - (8 - x)
4x+2x-10 = x-3-8-x
6x-10 = -11
6x = -11+10
6x = -1
X = -1/6
e) 9x - 2(x - 4x) = 3x - 2(3 - x)
9x - 2x + 8x = 3x - 6 + 2x
9x + 8x - 2x = 3x + 2x - 6
17x - 2x = 5x - 6
15x = 5x - 6
15x - 5x = - 6
10x = - 6
x = - 6/10
x = - 3/5
es todo espero haberte ayudado ✨✨
