Answer:

B.4

Step-by-step explanation:

1.5(x+4) - 3 = 4.5( x-2)-----------------------open brackets on both sides

1.5 x +6 -3= 4.5x- 9.................................collect like terms

3+9 = 4.5 x- 1.5x

12=3x..................................divide by 3 both sides to get x

12/3=x

x=4

ANSWER

x=4

EXPLANATION

The given equation is

[tex]1.5(x + 4) - 3= 4.5(x - 2)[/tex]

Multiply through by 10

[tex]15(x + 4) - 30= 45(x - 2)[/tex]

We expand to get:

[tex]15x + 60 - 30= 45x - 90[/tex]

Group similar terms to get;

[tex]15x - 45x = - 90 - 60+ 30[/tex]

[tex] - 30x = - 120[/tex]

[tex] x= 4[/tex]
