Answer:
-2
Step-by-step explanation:
Assuming you mean 60 + 6b = 48

Now divide both sides by 6 to solve for b: b = -12/6 = -2
Answer:
Josh has 29 coins.
Step-by-step explanation:
Let Terry have x coins then Josh has x + 12 coins.
Together they have x + x + 12 coins so we can form the equation:
x + x + 12 = 46
2x + 12 = 46
2x = 46 - 12 = 34
x = 17, so Terry has 17 coins and Josh has 17 + 12 = 29 coins.
