Answer:
x = 2
Step-by-step explanation:
x + 3 = -x + 7
Add x to each side
x+x + 3 = -x+x + 7
2x+3 = 7
Subtract 3 from each side
2x = 7-3
2x = 4
Divide by 2
2x/2 = 4/2
x = 2
I count 4 green stars and 6 red stars
ratio of green to red would be
4 green : 6 red
4:6
if you divide both numbers by 2, cause theyre both even
2:3
