(-7/4)= (-5)+y

y=(-7/4)+5

y=13/4)

(-7/4)-(13/4)= (-5)

(-13/4) should be subtracted from (-7/4) to get (-5)

Answer 2

Answer:

$let \: the \: number \: be \: x \\ \frac{ - 7}{ 4} - x = - 5 \\ \\ \frac{ - 7}{4} + 5 = x \\ \frac{ - 7}{4} + \frac{20}{4} = x \\ \frac{13}{4} = x \\ therefore \: we \: have \: to \: substract \: \frac{13}{4} from \frac{ - 7}{4} to \: get \: 5$
