Question

7th grade math help me pleaseeee

Answer 1

The lower left one.

Explanation:

If you expand and rearrange it, you will find out both of its constant cancel out, and leave you with 3w=3w. So w have infinite number of solutions.

Answer 2

`6((1)/(2) w-1)=3(w-2)`

Explanation:

`6((1)/(2) w-1)=3(w-2)` (Isolate parentheses)

`3w-6=3w-6` (Add six to both sides to isolate one variable w)

`3w=3w` (Divide by three to isolate variable w)

`w=w`

Because we got
`w=w`, that means that any number you put in for w will still get you the same answer, or "infinite answers." If you try, say 5, you would still get the same answer if you put in 9. It has infinite answers.

I hope this helped :)
