Answer:

x=3.33333

y=0.44444

Step-by-step explanation:

Would equal to

-8x-8y=24 -equation 1

16x+8y = -56 -equation 2 (because of multiplying both sides by 8)

=-24x=80 (minus-ing equation two by equation one, on all sides)

= 24x = -80 (switching around the signs)

x =3.3333

and...

y =0.4444

Rzqust [24]

Answer:

x=12

Step-by-step explanation:

For the given situation , a quantity x is added to $\frac{1}{4} x$ gives 15.

We can set up equation as

$x+\frac{1}{4}x=15$

Multiply each term by 4 on both sides to get rid the denominator.

It gives,

4 x+x=60

Now, combine like terms

5 x=60

Divide both sides by 5

x=12.
