Hi,
Applying the Distributive Principle and combining like terms..
will result in isolating x on one side of the equation, thus solving for x.
4x+5=3(x-1)
| Applying the distributive Principle
4x + 5 = 3x - 3
Proceeding to combine like terms and isolate x on one side of the equation
| subtracting 3x from both sides of the equation
4x -3x + 5 = 3x -3x - 3
x + 5 = -3
| Subtracting 5 from both sides of the equation
x + 5 - 5 = -3 - 5
x = -8
Always feel free to post questions of a general nature with an example,
as You did here.

4x%2B5=3%28x-1%29<-- Distribute the 3 on the right hand side.
4x%2B5=3x-3
4x-3x%2B5=3x-3x-3<-- Subtract 3x from both sides
x%2B5=0-3
x%2B5=-3
x%2B5-5=-3-5<-- Subtract 5 from both sides
x%2B0=-8
highlight%28x=-8%29
