4x - 9 = 10x
combine like terms on each side
4x - 4x -9 = 10x - 4x
-9 = 6x
6x = -9
divide equation by the coefficient of x to get x all by itself
(6x)/(6) = -9/6 = -3/2
x = -3/2

Subtract 4x on both sides:
-9=6x
Divide 6 on both sides:
x=-9/6=-3/2 or -1.5
Check:
4(-3/2)-9=10(-3/2)
-6-9=-15
-15=-15

4x-9=10
1. choose which side your going to solve on. i would pick 10x
2. subtract 4x from 10x 10x-4x=6x
3. there for you have 9=6x
4. divide 6 by each side 6x/6=x 9/6=1.5
5. x=1.5

4x-9=10x
4x-10x=9
-6x=9
x= -9/6
x= -3/2

first you subtract 4x from both sides. so you get 10x-4x= -9
then you do the subtraction 6x= -9
then divide
-9/6= x
Then simplify.
3 goes into both. so -3/2 or = -1 1/2

4X-9=10X
-4X+4x-9=10X-4X
-9=6X
-9/6=6X/6
-3/2=X
check
(-3/2*4)-9=10*-3/2
(-12/2)-9=-30/2
-6-9= -15
-15= -15
