Hey!
First, we'll have to distribute -3 into ( x + 5 ).
Old Equation :
4x - 3 ( x + 5 )
New Equation {Old Equation Distributed} :
4x - 3x - 15
Now, we'll add similar elements, those being the numbers that contain the variables.
Old Equation :
4x - 3x - 15
New Equation {Added Similar Elements} :
x - 15
So, this means that the expression 4x - 3 ( x + 5 ) is x - 15.
Hope this helps!
