we have

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

Applying distributive property both sides

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

[tex]1.5x+6-3=4.5x-9[/tex]

Group terms that contain the same variable, and move the constant to the opposite side of the equation

[tex]4.5x-1.5x=6-3+9[/tex]

[tex]3x=12[/tex]

Divide by [tex]3[/tex] both sides

[tex]x=4[/tex]

therefore

the answer is

[tex]x=4[/tex]
