4 is the answer because for every green balloon there are 4 red balloons
Zero pairs are basically 2 numbers that add up to zero like -1 +1 = 0 they cancel each other out. By assigning tiles to represent each number, you can cancel out the zero pairs and the remaining tiles will represent the sum or difference of the numbers.

Solution:
, 
Step-by-step explanation:
<u>System of Equations</u>
Solve the system:
x + 4y = 14
3x - 2y = 7
using the elimintation method.
To use the elimination method, we must add or subtract both equations in such a way that one of the variables goes away, and only one remains.
It requires to multiply one of them by a specific factor to match the coefficients. For example, multiply the first equation by -3:
-3x - 12y = -42
And add it to the second:
3x - 2y = 7
To result:
-14y = -35
Divide by -14:

Simplifying:

Now calculate x:
