I find it easier to see if I have a picture.
Answer:
The equation has infinity solutions
Step-by-step explanation:
we have

Applying distributive property left side

Combine like terms

The linear equation of the left side is equal to the linear equation of the right side
Both lines are identical
therefore
Is a consistent dependent system
The equation has infinity solutions
2q+18=-5q-3
2q+5q=-3-18
7q=-21
q=-3
If you have 3/5 marbles and you got 4/3more marbles then all you have to do is:3/5 x 3/3 and get 9/15.For 4/3 you multiply 4/3 x 5/5 and get 20/15.You simplify this and get 1 5/15.Now all you do is add them and get 1 14/15. Hope this helped you :-).
360 degrees is a full turn, so if you multiply 30 degreed by 12, you go around in a circle.
