-10=-14v%2B14v.... .this equation you need to solve for v

-10=highlight%28-14v%2B14v%29...since you have -14v and -14v, their sum is equal to zero; so, there is NO solution


a-2%2B3=-2....this equation you need to solve for a
a-2%2B3=-2...cancel -2 on both sides
a-cross%282%29%2B3=-cross%282%29
a%2B3=0..add -3 to both sides
a%2B3-3=0-3
highlight%28a=-3%29.solution

I need explanations on these math problems.
--------------------
-10=-14v+14v
This is a contradiction.
It says -10 = 0
---
No solution
====================================

a-2+3=-2
---
a + 1 = -2
---
a = -3
