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]
