1: Triple the quantity of a number “n” plus 4 equals 27. what would the expression look like?

[ Triple the quantity of a number “n” ] 3n

[ plus 4 ] + 4

[ equals 27 ] = 27

[ Seventeen equals ] 17 =

[ seven less than ] - 7

[ three times a number “n” ] 3n

[ all together ] <u>17 = 3n - 7</u>

<u />
