<span>Pint is half size of a quart, so the conversion factor from pints to quarts is 0.5 (It's the same for fluid and dry measurement). To find out how many quarts in pints, multiply by 0.5 or instead,
so 13 pints in quarts is 6.5

Answer:
x = -7
Step-by-step explanation:
4x-9 = 7x+12
Add 9 to both sides
4x = 7x + 21
Subtract 7x from both sides to further isolate the variable
-3x = 21
Divide both sides by -3
x = -7
Plug the value in to check your work:
4(-7) - 9 ? 7(-7) +12
-28 - 9 ? -49 + 12
-37 ? -37
-37 = -37
