Add 7 to both sides
Y+7=3
Divide both sides by 3
Y+7/3=x
Switch sides
X=y+7/3
The barista used 16 cups of milk. I know, I know, I'm super cool, just rate me 4 stars or better, its really the only way you can repay the massive debt you owe me.
X² + y² = 225
x - 7y = -75
x = 7y - 75
x² + y² = 225
(7y-75)² + y² = 225
(7y - 75)(7y - 75) + y² = 225
49y² - 525y - 525y + 5625 + y² = 225
50y² - 1050y + 5400 = 0
50(y² - 21y + 108) = 0
y² - 21y + 108 ⇒ (y - 12)(y - 9)
x = 7(12) - 75
x = 84 - 75
x = 9 ⇒ (9,12)
x = 7(9) - 75
x = 63 - 75
x = -12 ⇒ (-12,9)
