-(-2x-6y=-16)
2x+6y=16
4x-6y=-58
Y's cancel out, then add the rest
6x=-42
divide both sides by six
x=-7
plug x into any previous equation
2(-7)+6y=16
-14+6y=16
6y=30
y=5
Step-by-step explanation:
(Hope this explanation can ease your mind a little if possible! Alright let's go! :D)
Let n be the middle of the 3 consecutive even integers. Therefore, (n - 2) and (n + 2) are the smallest and largest of the 3 numbers respectively.
We know that (n - 2) + n + (n + 2) = 78,
so 3n = 78, and n = 78/3 = 26.
Since the middle number is 26, the smallest number is 26 - 2 = 24 and the largest number is 26 + 2 = 28.

Answer:
We need the hourly rate for renting the bicycle. Assuming that the rate is Rb, we can state: Cb = AED5.00 + Rb*x for renting a bicycle for x hours
Step-by-step explanation:
Assuming that the rate for renting a bicycle is Rb, the cost (in AED), Cb (in AED/hr), of a bicycle rental for x hours would be:
Cb = AED5.99 + Rb*x
Assuming the transportation fee applies, the cost of renting a canoe for 6 hours would be: AED = 5 + 2.00*6 , or AED17 for 6 hours
Answer:
x² + x + 8 = 0
Step-by-step explanation:
Given
(x - 2)² + 5(x + 2) - 6 = 0 ← expand (x - 2)² and distribute parenthesis by 5
x² - 4x + 4 + 5x + 10 - 6 = 0 ← collect like terms on left side
x² + x + 8 = 0 ← equivalent quadratic equation
