eimsori [14]

Answer:

y = (2x/9) + 1

Step-by-step explanation:

Solving for y we get 3(-2y+x) = 5(-3y+x)+9

Expand the above we get -6y+3x=5(-3y+x)+9

which is -6y+3x = -15y+5x+9

then 9y = 2x+9

which y = (2x/9) + 1

The answer after division is: $2\frac{2}{5}$

Step-by-step explanation:

The given question involves two mixed fractions that are being divided.

$7\frac{1}{2}\div 3\frac{1}{8}$

First of all, we will convert the fractions into proper fractions

$\frac{15}{2}\div \frac{25}{8}$

When the division is performed, the second fraction is reversed

So dividing gives us:

$\frac{15}{2} * \frac{8}{25}\\= \frac{3*4}{5}\\=\frac{12}{5} = 2\frac{2}{5}$

Hence,

The answer after division is: $2\frac{2}{5}$
