For this case we must solve the following equation:
[tex]5x-27 + 7x-32 + 9x-8 = 180[/tex]
We group the variable terms of the left side of the equation, the terms that are adding from one side pass to the other side subtracting and vice versa:
[tex]5x + 7x + 9x = 180 + 27 + 32 + 8\\21x = 247\\x = \frac {247} {21}\\x = 11.76[/tex]
Thus, the value of the variable is 11.76
ANswer:
[tex]x = 11.76[/tex]
