Practice solving multis
ASSIGNMENT
Solve 3[-X + (2 x + 1)] = x-1.

We need to solve this equation:

Firstly, we remove the parenthesis, as it's getting summed and it isn't necessary:

Now we operate the brackets:

We calculate tha prenthesis:

And finally, we substract x and 3 on both sides. a

Now, we can verify for x = -2:

TRUE

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

i don't know, but that looks pretty bad. my school passed us unless we failed in all the subjects, but idk abt ur school's rules.
