x^2-xy+3y^2=15 x-y=2
Make the equation X:
x = y + 2
Plug in and Solve:
(y+2)^2 - y(y+2) + 3(y+2)^2 = 15
y = (√46) - 7/3
y = - 7 + (√46)/3
Answer: 7
Step-by-step explanation:
Find the prime factors of each term in order to find the greatest common factor (GCF).
Is there a picture that I can use to view where the angle of angle 7 is at?
The last one, v = -2,000y + 20,000
