Question 648193
Original equation: {{{5+ (-12) + (4t)}}}

Step 1: We're going to begin by rewriting this equation so it's easier to look at

{{{5+ (-12) + (4t)}}}

The {{{5}}} is technically subtracting the {{{(-12)}}}

{{{5 - 12 + 4t}}}

Step 2: Combine like terms

{{{5 - 12 + 4t}}}

{{{5-12=-7}}}

{{{-7 + 4t}}}

The most simplified version of the equation is {{{-7 + 4t}}} or {{{4t-7}}}
