Respuesta :

1. We must solve the equation

[tex]15=3(2x+4)-3[/tex]

in order to find the value of x.

2. Because of the addition property of equality, if we add 3 to both sides of the equation we get

[tex]18=3(2x+4)[/tex]

3. We multiply the 3 on the right side of the equation by what's inside the parentheses (2x+4) and we get

[tex]18=6x+12[/tex]

4. Because of the subtraction property of equality, if we subtract 12 from both sides of the equation, it results in

[tex]6=6x[/tex]

5. Because of the division property of equality, if we divide both sides of the equation by 6, then

[tex]1=x[/tex]

6. Thus,

[tex]x=1[/tex]
