You need to get the variable by itself, right? To do that, you need to get rid of the -4.8, and to do <em>that</em>, you need to add 4.8 to each side. -4.8 + 4.8 is 0. -7.12 + 4.8 is -2.32 (because you're adding them; however, since the number with the negative is larger, you keep the sign).
Your answer is -2.32 <em> Don't forget to choose which answer is Brainliest!</em>
