Step-by-step explanation:
I think its 2x +3x=21 because you can plug in the numbers?
Put the same variable on the same side first than solve
Where is the question????
<em>9/-1</em>
<em />
Because you do what’s in parentheses first which is (6+3)
You get the answer 9
Then you do 4-5 which will lead to going into negative numbers and the answer will be -1
So 9/-1 or Nine divided by negative one
13+3k=11
-Move constant to the right-hand side and change its sign
3k=11-13
Calculate the difference
3k=-2
Divide both sides by 3
K= -2/3
