Question

resuelve:

a) 3x+2=x-6

b)-y-1=5+y

c) x+8+3x-3=2x-3

d) 1+x=5-x

e) z-2=-3z-10

f) x+8/2=x

(Ayuda Porfa)

Answer 1

3x+2=x-6 
3x - x = - 6 - 2
2x = - 8
x = - 8/2
x = - 4



-y-1=5+y
- y - y = 5 + 1
- 2y = 6
y = 6/-2
y = - 3



x+8+3x-3=2x-3 
4x + 5 = 2x - 3
4x - 2x = - 3 - 5
2x = - 8
x = - 8/2
x = - 4



 1+x=5-x
x + x = 5 - 1
2x = 4
x = 4/2
x = 2



z-2=-3z-10
z + 3z = - 10 + 2
4z = - 8
z = -8/4
z = - 2



x+8/2=x 
(x * 2 + 8)/2 = x
(2x + 8)/2 = x
2x + 8 = 2x
2x - 2x = 8
0x = 8
