Answer:
Yea its correct! good job yea there are not any mistakes
Step-by-step explanation:
7x. Try to ignore the X's for a second and think of the problem as -12+5 (aka 5-12). The answer to that is 7. now add the x back again to get: 7x
2m+3v=23
4m+8v=56
-2(2m+3v=23)
-4m-6v=-46
4m+8v=56
2v=10
v=5
plug in v
2m+15=23
2m=8
m=4
movies=$4
video games=$8
