ANSWER
The solution is
x=-3,y=-2
EXPLANATION
First equation
3x – 3y = –3
Second Equation:
5x – y = –13
Multiply the second equation by 3 to get:
Third equation:
15x-3y=-39
Subtract the first equation from the third equation:
![15x - 3x = - 39 - - 3](https://tex.z-dn.net/?f=15x%20-%203x%20%3D%20%20-%2039%20-%20%20-%203)
![12x = - 36](https://tex.z-dn.net/?f=12x%20%3D%20%20-%2036)
Divide both sides by 12,
![x = \frac{ - 36}{12} = - 3](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B%20-%2036%7D%7B12%7D%20%20%3D%20%20-%203)
Put x=-3 into the first equation:
![3( - 3) - 3y = - 3](https://tex.z-dn.net/?f=3%28%20-%203%29%20-%203y%20%3D%20%20-%203)
![- 9 - 3y = - 3](https://tex.z-dn.net/?f=%20-%209%20%20-%203y%20%3D%20%20-%203)
Group like terms,
![- 3y = - 3 + 9](https://tex.z-dn.net/?f=%20-%203y%20%3D%20%20-%203%20%2B%209)
![- 3y = 6](https://tex.z-dn.net/?f=%20-%203y%20%3D%206)
![y = - 2](https://tex.z-dn.net/?f=y%20%3D%20%20-%202)
The solution is
x=-3,y=-2

Answer:
do not sell them
Step-by-step explanation:
bc i alredy did
y = -
x - 34
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 68, 0 ) and (x₂, y₂ ) = (0, - 34 )
m =
=
= - ![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
the y-intercept = (0, - 34 ) ⇒ c = - 34
y= -
x - 34
