3x plus 9 equals what?
3x+5=14 3x=9 x=3
the answer is -3x = 0
-3x + 2y = 9 2y = 3x + 9y = 1,5x + 4,5
3a + 9 =3X(a + 3)
3x - 3 = 2x + 6 3x = 2x + 9 x = 9
3x plus 9 equals what?
3x+14 = 23 so 3x = 9 and so x = 9/3 = 3
24 = 3x + 9 -9 -9 Subtract 9 from each side15 = 3x/3 /3 Divide 3 from each side5 = x You are left with five equals X
50, 53, 59
-2x+9=x+1-x........-x-3x+9=1.....-9...-9-3x=-8-3x/-3 | -8/-3\ /........\ /x=8/3
Yup
3x+5=14 3x=9 x=3
equivalent to 3x -6 = -9; so 3x = -9 + 6; so 3x = -3 so x = -1. Check: -6 + (3 * -1) = -6 + (-3) = -9 QED
3x + 7 = 3(-3) + 7= -9 + 7= -2
27-9 =18. 18/3 =6
the answer is -3x = 0
