Original equation: 5%2B+%28-12%29+%2B+%284t%29
Step 1: We're going to begin by rewriting this equation so it's easier to look at
5%2B+%28-12%29+%2B+%284t%29
The 5 is technically subtracting the %28-12%29
5+-+12+%2B+4t
Step 2: Combine like terms
5+-+12+%2B+4t
5-12=-7
-7+%2B+4t
The most simplified version of the equation is -7+%2B+4t or 4t-7
