6y - 2 = 2y + 8 : Subtract 2y from both sides
4y - 2 = 8 : Add 2 to both sides
4y = 10 : Divide both sides by 4
y = 10/4 = 2.5 or 21/2
3(2y + 3)(y + 2)
(3x+2y)*(5x-3y) =3x*5x + 3x*(-3y) + 2y*5x + 2y*(-3y) [This is sometimes called the FOIL method - You multiply the First members of each bracket, then the Outers, Inners, Lasts] = 15x2 - 9xy + 10xy - 6y2 = 15x2 + xy - 6y2
(-1, 5)
(-1, 5)
This means that 2y - 3 = 2y + 4 which is not possible.
No 2y-3 is not equals y plus 2AND how old are u?
2y+3y-7y+4=16 -2y=12y=-6Check it-12-18+42+4=16-30+46=1616=16
Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
(3, 2)
2y+26 = 28 2y = 28-26 2y = 2 y = 1
5y-7 = 2y+11 (+7 to both sides) 5y = 2y+18 (- 2y from both sides) 3y = 18 (divide both sides by 3 ) y = 6 y=6
-2y=x+8 is the answer
