It is asking us to write it in numerical form.
We have "double 9" which means 2(9).
"add 27" is +27.
If we combine those two together, we get
$2(9)+27$ .
If you want the answer we do 2*9=18, then 18+27=45

-5x + 4 = 2x + 16<br> How do I solve this

Cloud [144]

Subtract 2x from both sides then you’d have -7x+4=16 Then you subtract 4 from both sides and you’d get -7x=12. Next you divide both side by -7 so x=1.75 rounded to the nearest hundredth.
