What does 3 minus 6x equals 4x plus 9?

Answer 1

3 - 6X = 4X + 9

subtract 4x from each side

3 - 10X = 9

subtract 3 from each side

- 10X = 6

divide each sides integers by - 10

(- 10/- 10)X = 6/- 10

X = - 3/5

==========check in original equation

3 - 6(- 3/5) = 4(- 3/5) + 9

3 + 18/5 = - 12/5 + 9

now, 3 = 15/5 and 9 = 45/5

15/5 + 18/5 = - 12/5 + 45/5

33/5 = 33/5
