Answer:
Step-by-step explanation:
12x - 20 = 6( x - 20) - 9x
pay attention to the brackets as you simplify.
Let's work on it:
12x - 20 = 6x - 120 -9x
Collecting like terms to further simplify the equation.
12x - 6x + 9x = -120 + 20
15x = -100
Let's make x the subject formula by dividing through by 15
Therefore:
x = -100 / 15
Divide through by 5
x = -20 / 3
Since nothing can easily divide through, we turn it to a mixed fraction
x = - 6 2/3
( Minus six whole number, two divided by three)
