You can tell if it is going to be negative if there is a number with a greater value. for example -14 minus 7. that would be -7
You can tell if it is positive if one number has a bigger value. for example 12-(-6)=6
And if it is zero it would be something like this
-7+7 sorry that's hard to explain in words hoped this helped you
It is simple
Step 1) substitute x = 5 into the equation
3x +4
3(5) + 4 gives you 3 times 5 + 4
The answer is 15 + 4 which is 19
Now substitute a and b into the equation 3(a) + 4(b) when the a = 6 and b = 5
Hereby 3(6) + 4(5)
3 * 6 = 18 and 4* 5 = 20
18 + 20 = 38
The answer is 38
Now finally
Substitute a and b Into the equation
3(3) + 4(6)
9+ 24 = 33

Answer:
Step-by-step explanation:
The problem statement tells us ...
8x = y +3
7x = y -4
Subtracting the second equation from the first gives ...
x = 7
Then ...
y = 7x +4 = 7·7 +4 = 53
There are 7 people, and 53 coins are required for purchase.
