Answer:

<h3>y=14, and x=-2</h3><h3>(-2,14)</h3>

Step-by-step explanation:

Isolate the term of x and y from one side of the equation.

y=4x+22 and y=-7x

y=-7x=4x+22

Solve.

-7x=4x+22

x=2

Substitute.

y=-7x, x=-2

y=-7(-2)

Solve.

Multiply.

<u>y=14</u>

<u />

<u>(-2,14)</u>

Therefore, the final answer is (-2,14).

I hope this helps you! Let me know if my answer is wrong or not.

At the restaurant there is 7% sales tax. If the bill was $8.64, how much would be owed in total.
nlexa [21]
$9.24 would be the total (couple extra decimals after it do not count as it's not counted over in real life nor could a penny be split)

C D E
9 2
Because the line CE is 11, you will need to subtract it by 9 to find line DE.
11-9=2
To check your work you may add 9 and 2 to find out if it comes out to 11 and it does.
