Haha, you first start off with adding 3 to both sides, cancelling the -3, and adding it to 9. you end up with 5x=12, in which you divide both sides by 5. you get 2 and 2/5 or 12/5! hope that helps :)
The answer would be 7x+ 17
Multiply 13 by the 2 above the divide line
13*2 = 26
so the number in the box should be 260
Answer:
x = -2
Step-by-step explanation:
You have -5x + (-2) = -2x +4 add 5x on both sides and you will have
-2 = -2x + 5x +4 simplify
-2 = 3x + 4 add -4 on both sides
-2 -4 = 3x
3x = -6 divide both sides by 3
x = -2
