Answer:
The answer is D
You have to distribute the x to the 2x + 3 equation
This will result in 2x^2 + 3x
X = -4y+3
-x-4y = -3
________________
x+4y = 3
-x-4y = -3
0 = 0
Possible and determined system (single solution)
Answer:
x = 27.8, y = 35
Step-by-step explanation:
Angle D is equal to Angle A
Angle E is equal to Angle B
Angle F is equal to Angle C
So you can set those equal to each other:
2y - 5 = 65
2y = 70
y = 35
-------------------------
2x + y = 90.6
2x + 35 = 90.6
2x = 55.6
x = 27.8
