Hey!
Alright, let's take a look at this problem.
The first step would be to rearrange the equation. To do that we will group the like elements.
Original Equation :
7x - 8 - 3x - 4
New Equation {Changed by Grouping Like Elements} :
7x - 3x - 4 - 8
Next, we'll add both the 7x and 3x since they both contain variables.
Old Equation :
7x - 3x - 4 - 8
New Equation {Changed by Adding Similar Elements} :
4x - 4 - 8
Again, we'll add the other similar elements in the equation.
Old Equation :
4x - 4 - 8
New Equation {Changed by Adding Similar Elements} :
4x - 12
Our equation can no longer be simplified any farther, so we have our final answer.
The equation 7x - 8 - 3x - 4 simplified is 4x - 12.
Hope this helps!
