Answer :
simplify by distributing
distribute the - to (9x - 10) and distribute 3 to (-2x+1/3)
so x-9x +10 + 11 = 12x - 6x +1
simplify: -8x +21 = 6x + 1
put like terms on each side
20 = 14x
20/14 = 10/7 = x
distribute the - to (9x - 10) and distribute 3 to (-2x+1/3)
so x-9x +10 + 11 = 12x - 6x +1
simplify: -8x +21 = 6x + 1
put like terms on each side
20 = 14x
20/14 = 10/7 = x
Answer: x = 10 / 7
Step-by-step explanation:
X - (9x - 10) + 11 = 12x + 3 (-2x + 1/3)
To simplify this, we have to first open the bracket
x - 9x +10 + 11 = 12x - 3(-2x) + 3(1/3)
x - 9x + 10 + 11 = 12x - 6x + 1
-8x + 21 = 6x + 1
We will now collect like term
(which implies 8x will move to the right hand side hence it becomes positive 8x and then 1 will move to the left hand side hence it becomes negative 1)
21 - 1 = 6x + 8x
20 = 14x
Now, we divide both-sides of the equation by 14
Hence;
[tex]\frac{20}{14} = \frac{14x}{14}[/tex]
[tex]\frac{20}{14}[/tex] = x
x = [tex]\frac{20}{14}[/tex]
Dividing the numerator and the denominator by 2, x becomes;
x = [tex]\frac{10}{7}[/tex]
