First, we need to isolate the variable x.
To isolate x, we simply need to multiply both sides by 9, which would result in x = 9
Answer:
a=1, b=2, c=5, d=1, e=6
Step-by-step explanation:
So 
The factors of 40 from that list are 4, 8. and 80. A factor needs to be able to be divided by 40.
Don’t keep your cool and tell her after class or tell her “Can you not”
here's the equation: x+x+(x+12)+ 1/2(x+12) =81
combine like terms
(x+x+x+1/2x) + (12+6) = 81
simplify
7/2x +18=
subtract 18 from both sides.
7/2x=63
multiply by reciprocal (aka 2/7)
x=18
18+12=30 so celia gave 30.
Hope this helps!
