5 x - 5 = 9 x + 3
Move variable to the left-hand side and change its sign
5 x - 9 x - 5 = 3
Move constant to the right-hand side and change its sign
5 x - 9 x = 3 + 5
Collect like terms
- 4 x = 3 + 5
Add the numbers
- 4 x = 8
Divide both sides of the equation by 4
X = - 2
And you answer is x = - 2

x=-2
Step-by-step explanation:
To solve the equation, we want to find out what x is. In order to do this, we have to get x by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.
5x-5=9x+3
9x is being added to 3. The opposite of addition is subtraction, so subtract 9x from both sides.
5x-9x-5=9x-9x+3
5x-9x-5=3
-4x-5=3
5 is being subtracted from - 4x. The opposite of subtraction is addition, so add 5 to both sides.
-4x-5+5=3+5
-4x = 3+5
-4x=8
x is being multiplied by 4. The opposite of multiplication is division, so divide both sides by - 4.
-4x/-4=8/-4
x=8/-4
x = - 2
