Question

a) 2 - x= r -8
b) 2x – 1= 5x + 8
c 3 3x – 1= x2 + 2x
g) 2/1 – 2 = 10
e) 2(3x - 2) = 2
f) -2(3x - 2) = -2​

Answer 1

Respuesta:

b) 2x -1=5x+8

2x-5x=8+1

-3x=9

x=9/-3 = -3

c)33x-1 = x2 +2x

-1 =x2 + 2x -33x

-1 =x2 -31x

-1 = x(x2-33x)

-1 = 1^2 -33 = -33

d) 2/1 -2 =10

=10

e)2(3x-2)=2

3x -2 =2/2

3x-2 = 1

3x = 1+2

3× = 3

x =3/3 = 1

f) -2(3x - 2 ) =-2

(3x-2)=-2/-2

3x = 1+2

x =3/3= 1
