if 2x+3=9 then 2x=6 so x=3
x = y+3 x+2y = 9 => x = 9-2y y+3 = 9-2y 2y+y = 9-3 3y = 6 y = 2 and x = 5
7(3y-2)-(-4y+9)
3x plus 9 equals what?
3a + 9 =3X(a + 3)
9 8w - 17 = -89 ie 8w = -89 + 17 = -72 w = -9
-36 + 2w = -8w + w -36 + 2w = -7w -36 = -7w - 2w -36 = -9w w = -36/-9 = 4
No! It equals 15, but 9-6=3.
-9 + 3 = -6
96
9
-9 + 6 = -3.
42
x=3
If I am correct, 9 plus 7 equals 112.
-3+9 is the same as 9-3=6
3 + 9 = 12
