Answer 1

Where you've stucked?

i distributed, but i dont know what to do with the +6.

Answer 3

Can you show what you've done thus far?

Answer 4

1) Distribute first.
\(\Large \color{MidnightBlue}{\Rightarrow 3x + 3 = -2x + 2 + 6 }\)

2)Operate on like terms.
\(\Large \color{MidnightBlue}{\Rightarrow 3x + 3 = -2x + 8 }\)

3) Add 2x to both sides.
\(\Large \color{MidnightBlue}{\Rightarrow 5x + 3 = 8 }\)

4) Subtract 3 from both sides.
\(\Large \color{MidnightBlue}{\Rightarrow 5x = 5 }\)

5) Divide both sides by 5.
\(\Large \color{MidnightBlue}{\Rightarrow x = 1 }\)

Answer 5

Multiply -2 by each term inside the parentheses.
3(x+1)=-2x+2+6
Add 6 to 2 to get 8.
3(x+1)=-2x+8
3x+3=-2x+8
solve from here?

Answer 6

You must isolate the x.
