Answer:
3(4+x)
which can be simplified to 12+3x
-2 is a solution because first you subtract 4x then after you get a new equation you move 15 to the left, then you subtract 15 from -1, then you factor the left side, then you divide both sides of the equation by 2
4 x minus four-fifths = 2 and one-fifth; x = three-fourths of a pound
