Answer:
A. 2x, -4y, and 8
Step-by-step explanation:
If there is a minus sign in front of the 4 (-), add that to the expression. What you are just simply doing is separating the numbers up. For example:
12x - 8y + 4x
Now here, you have two of the same variables (x, y, etc). So, what you do is look at the last number that has the same variables, which is 4, and look at what the problem you will be solving, which is addition. So, very simply, you add then together!
12× + 4× = 16×
As you can see I kept the same variable. This is because, well, it is the same! Simply, just substitute in the 16× with the 8y. Now here is the tricky part, for some people. Do you see that there is a negative sign in front of the 8 (-)? Well! You have to substitute that in with the expression. No adding this or anything, just simply slide it next to the 16× because, we can not add nor subtract it with the 8y just because it has a different variable.
Your example answer would be: 16× - 8y
Hope this helps!

Answer:
FH=7
Step-by-step explanation:
If the whole thing FG is 22 and HG is 15 you subtract 22-15 and get 7
I guess no solution
4x +3 = 4X + 18
4X - 4X = 18 - 3
0 = 15
75%
30/40 means its 75% out of 100%
75$ representing the 30 and the 100$ representing the 40
