In the given problem, you need to apply your knowledge and skills in alegbra and basic math.
Problem
Find the number
Solution
Let x stands for a number
The equation based from the statement
13 = 2x + (6)(1/x+3)(4)
Then simplify and solve for x
13 = 2x + 24/(x+3)
The GCF is x + 3
(x + 3)(13 = 2x + 24/(x+3))
13x + 39 = 2x^2 + 6x + 24
2x^2 + 6x - 13x + 24 - 39 = 0
2x^2 - 7x - 15 = 0, solve for x using factoring
(2x+3)(x-5) = 0
2x + 3 = 0, x = -3/2
x - 5 = 0, x = 5
Therefore, the unknown number is -3/2 and 5.
