9x-7x= 2x
because both are x's now u cant add nor subtract anything to Y so just leave it alone but u can add 6+14
2x+8y=20

Hope this helps
Answer: k = 12
<u>Step-by-step explanation:</u>
x² + kx + 36 = 0
In order for x to have exactly one solution, it must be a perfect square.
(x + √36)² = 0
(x + 6)² = 0
(x + 6)(x + 6) = 0
x² + 6x + 6x + 36 = 0
x² + 12x + 36 = 0
k = 12
Step-by-step explanation:
14 < 6×?
6×3=18
therefore anything above 3 multiplied by 6 would be greater in value than 14
x = -3, y = -2
Substitute the values of x and y to the equation xy = k:
k = (-3)(-2)
k = 6
