I need some step my step notes on how to solve systems of equations like this for example

System of equations:

• Equation 1

• Equation 2

Procedure

This system is easier if we solve it using the elimination method, in which we multiply the first equation times minus one, add both equations to eliminate the x variable, and solve for y.

0. Multiplying Equation 1 times minus 1.

2. Adding both equations:

Then:

3. Finally, substituting this value in any equation and solving for x:

y = 9 and x = -5.

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.
