Question
Solve the equation: -5x+9=3

Answer
Solving this equation means that we need to find the value of x. Below are the steps to do so:


-5x+9 = 3
To find the value of x, we need to put all the terms with x on one side of the equation  and the terms without x to the other side.
-5x+9-9 = 3-9
To do so, first, we add -9 to both sides of the equation.
-5x = 3-99 and -9 cancels off and 3-9 gives -6.
-5x = -6
Next, notice that to find x, we need to remove -5.
(-5x)/(-5) = (-6)/(-5)
To do so, we divide both sides of the equation with -5.
Two of the -5 cancel off
The two -5 cancel off each other.
x = (-6)/(-2)
Finally, we can find x by dividing -6 with -5.
x = 1.2
This gives x as 1.2.
