First, subtract 58 from both sides and you get: 12y = -54
Then divide both sides by 12 and you get: y = -4.5
12y + 5 = 53 12y = 48 y = 4
12y - 4 = 7y + 165y = 20y = 4
The given equation: =3x-4x plus 9xy-12y =3x-4x+9xy-12y =-x+9xy-12y =-x+3y(3y-4) Answer.
y(3y^2 - 12y + 4)
4(3y+4)
3y + 4z + 12y = 3y -3y -3y ------------------------- 4z + 12y = 0 divide everything by 4 z + 3y = 0 -3y -3y z = -3y
6y + 4.. i think
13x - 9y - 10
14.5
58
4 + 58 - 22 = 40
4 complete feet plus 10 inches left over (that would be a fraactional amount) equals 58 inches.
