Hello from MrBillDoesMath!
Answer: x = +9
Discussion:
-59 = 3x -2 (7x -20) or
-59 = 3x - (2*7)x - 2 ( -20) or
-59 = 3x -14x + 40 or
-59 = -11x + 40. Subtract 40 from each side
-59 - 40 = -11x or
-99 = -11x
or x = + 9
Thank you,
MrB
The number of birds is an illustration of ratio and proportions, and Emma is 5 years old
<h3>How to determine Emma's age?</h3>
From the complete question, Emma's age is the sum of the simplified ratio between the number of birds.
The ratio can be represented as:
Birds = 200 : 300
Simplify the ratio
Birds = 2 : 3
Add the numbers in the above ratio
Emma = 2 + 3
Emma = 5
Hence, Emma is 5 years old

Answer:
x₁ = 4
x₂ = 2
Step-by-step explanation:
x² - 6x + 8 = 0
x² - 2x - 4x + 8 = 0
x(x - 2) - 4(x - 2) = 0
(x - 4)(x - 2) = 0
x - 4 = 0 => x₁ = 4
x - 2 = 0 => x₂ = 2
