Step-by-step explanation:
3/4x+3-2x=1/4+1/2x+5
x=2/-3
First you need to find the middle number, wich is 75. Since there is no $75, I would go with $80.
F<span>irst you set up a proportion 18 over ? = 60 over 100 then cross multiply. 18*100=1800 then divide that by 60 and you get 30
or
</span>18/60=x
0.30=x
30
hope this helps!!!!
x=6, add thirty to both sides 6 squared is 36, plus six is 42
