Answer:

-24

Step-by-step explanation:

3(x+24-4x+24)-11=61-12x

3(-3x+48)-11=61-12x

-9x+144-11=61-12x

-9x+12x=61-144+11

3x=-72

divide both sides by 3

3x/3=-72/3

x=-24

Answer:

x = -24

Step-by-step explanation:

[tex]3[x+4(6-x)+24]-11=61-12x[/tex]

Expand:

[tex]3(x+24-4x+24)-11=61-12x[/tex]

Simplify:

[tex]3(-3x+48)-11=61-12x[/tex]

Expand again:

[tex]-9x+144-11=61-12x[/tex]

Simplify:

[tex]-9x+133=61-12x[/tex]

Subtract 133 from both sides:

[tex]-9x=61-12x-133[/tex]

[tex]-9x=-12x-72[/tex]

Add 12x to both sides:

[tex]3x=-72[/tex]

Divide 3:

[tex]x=-24[/tex]
