The answer to this equation is 1412 or 21-15
Collect like terms
6.5x-4.5x = 6+10
2x = 6+10
Divide both sides
2x = 16
X= 8
Step-by-step explanation:
Divide by any number except 0 means the same as multiply by its inverse.
The inverse of 
is 
Therefore
Used the commutative property of multiplication: a × b = b × a
Answer:
