Answer:

x=5, y=-5.6

Step-by-step explanation:

-8x-10y=24

6x+5y=2

-8x-10y=24

2(6x+5y=2)

-8x-10y=24

12x+10y=4

4x=20

x=5

6x+5y=2

6(5)+5y=2

5y=2-30

y=-28/5

y=-5.6

A house is valued at $118,000.00. The homeowner decides to add on a two-car garage that increased the value of the home by 15%.H

nasty-shy [4]

Answer:

The value of the house after adding the garage is $135,700.

Step-by-step explanation:

Given,

value of house before adding garage = $118,200.00

we need to find the value of house after adding two car garage.

Solution,

Since after adding two car garage the value of the house increased by 15%.

So firstly we will find out the 15% of the value of the house after adding garage.

So we can say that;

15% of the value of the house after adding garage is equal to 15 divided by 100 the multiplied with the value of the house before adding garage.

15% of the value of the house after adding garage = $\frac{15}{100}\times118,000=\$17,700$

Now, The value of the house after adding garage is equal to the sum of value of house before adding garage and 15% of value of house before adding garage.

We can frame it in equation form as;

The value of the house after adding garage = $\$118,000+\$17,000=\$135,700$

Hence The value of the house after adding the garage is $135,700.
