Answer:
(using substitution to solve the problem)
x=y-3
2x+y=12
2(y-3)+y=12
2y-6+y=12
3y=18
y=6
y=6
x=6-3
= (3, 6)
Step-by-step explanation:
using substitution, substitute the x in the second equation to y-3, to find the value of y. after that distribute the 2 into the parenthesis and collect like terms. once you simplify, you have the value of y, so substitute the value of y into the first equation to find x. once you have both values put them in the ordered pair form and you're done.

Answer:
The inverse is
<h2>

</h2>
Step-by-step explanation:

To find the inverse of the function interchange the terms that's x becomes y and y becomes x
We have

Now solve for y
<u>Move 3 to the other side of the equation</u>

Divide both sides by 3
We have

<u>square both sides of the equation to remove the square root</u>
That's

<u>Move 5 to the other side of the equation</u>

<u>Divide both sides by 2</u>
We have

<u>Find the square root of both sides</u>
We have the final answer as
