Hi,
For this question, we are given the following system of equations:
2x - y = 3
x + y = 3
Let's make the first equation in the form of y = mx + b as shown below:
y = 2x - 3
x + y = 3
Now, substitute the first equation into the second to get:
x + 2x - 3 = 3
Combine similar terms to get:
3x = 6
x = 2
We now know that x = 2 and can plug this value into one of the given equations to get:
2 + y = 3
y = 1
FINAL ANSWER: x = 2 ; y = 1
I hope that helps you out!
Your answer is going to be B.y-2=-3/8(x+4)

Answer:
83°
Step-by-step explanation:
Since angle x and angle y are supplementary angles,
x + y = 180°.
Since y = 97°
x = 180° - y = 180° - 97° = 83°
