Use substitution
Given both y values, you know that they have to be equal
3x + 3 = x - 1
2x + 3 = -1
2x = -4, divide by 2
x = -2
Now plug x value into any of the equation to find y value
y = 3(-2) + 3
y = -6 + 3, y = -3
Solution: x = -2, y = -3

Answer:
33k-15
Step-by-step explanation:
8k−5(−5k+3)
8k+25k-15 because -5(-5) equals=25. Two negatives equal a positive.
-5(3)= -15
So the equation changes to 8k+25k-15.
Combine like terms, and you get:
33k-15

The area of the garden
First, we calculate the length of the other side using:

This gives:

Divide both sides by 2

Make Side 2 the subject

So, the area of the garden is:

Answer:
$180
Step-by-step explanation:
Well because it is $27 per hour, you can start with the whole hours:
6*27=162
then because you are working with fractions you can find what 1/3 of 27 is:
27* (1/3)=9
this tells us that one-third of an hour is worth 9 dollars but because it is 2/3 then you just add another 9. This means 2/3 of 27 is 18.
Then you just add it all up:
162+18=180
