x-(9x-10)+11 = 12x + 3(-2x + 1/3)

I am not sure how to do this

expand first , then collect like terms

x - 9x + 10 + 11 = 12 - 6x + 1
-8x + 6x = 13 - 21
-2x = -8
x = 4

To solve this equation, we need to simplify both sides of the equation by combining like terms and then isolate the variable x. Let's go step-by-step:

1. Start by simplifying the equation on both sides:
x - (9x - 10) + 11 = 12x + 3(-2x + 1/3)

Distribute the negative sign inside the parentheses:
x - 9x + 10 + 11 = 12x + 3(-2x + 1/3)

Combine like terms on each side:
-8x + 21 = 12x - 6x + 1

Simplify further to get:
-8x + 21 = 6x + 1

2. Next, isolate the variable x by bringing all the x terms to one side and the constant terms to the other side. To do this, we can add 8x to both sides and subtract 1 from both sides:
-8x + 21 + 8x - 1 = 6x + 1 + 8x - 1

Simplify:
20 = 14x

3. Now, we can solve for x by dividing both sides of the equation by 14:
20/14 = (14x)/14

Simplify:
10/7 = x

So, the solution to the equation is x = 10/7.
