Answer 1

Answer:

$y = 46.4$

Step-by-step explanation:

$3y + \frac{4}{2} - 64 = - \frac{2}{5} \\ 3y - 64 = - \frac{2}{5} - \frac{4}{2} \\ 3y = \frac{4 + 20}{10} + 64 \\ 3y = \frac{24}{10} + 64 \\ 3y = \frac{464}{10} \\ 30y = 464 \\ y = \frac{464}{10} \\ y = 46.4$

Answer 2

Answer:

3y+4/2-64=-2/5

6y+4/2-64=-2/5

6y+4/2=-2/5+64

6y+4/2=-1+128/5

6y+4/2=127/5

6y+4/2 =63.5

6y+4=63.5×2

6y+4=127

6y=127-4

6y=123

y=123/6

y=2.5
