Simple. To change a variable/number's sign simply divide/multiply by a negative 1. So in this case divide both -y and 15-4x by a -1. To get your final answer you would flip the signs of the equation and since you divided by -1 only their signs will change. In the end you get \frac{-y}{-1} = \frac{15-4x}{-1}  or y=-15+4x

48 divided by four fifths
Fed [463]

Answer:

The answer is 60.

Step-by-step explanation:

\frac{48}{1}÷\frac{4}{5}

Now, apply the fraction rule(\frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}):

\frac{48}{1}×\frac{5}{4}

Cross-cancel(common factor of 4):

\frac{12}{1}×\frac{5}{1}

Multiply:

\frac{12 x 5}{1 x 1}

Simplify:

12 x 5=60

The answer is 60

hope this helps :)
