Answer:
x=2
Step-by-step explanation:
let the unknown number be x
now we are to find x regarding the question as an equation, let's form the equation to solve for x
the interpretation of the question is:
(x² + x)/3 = x
by collecting the like terms:
(x²+ x) = 3x
x² + x = 3x
x² = 3x - x
x² = 2x
x = 2
Answer:
63%

Answer:
x = 51
Step-by-step explanation:
the mean is calculated as
mean =
here mean = 11.5 , then
= 11.5 ( multiply both sides by 4 to clear the fraction )
- 5 + x = 46 ( add 5 to both sides )
x = 51
Answer:
The given equation which is in two variable is
⇒2 x + y =9
As we know that to get a unique solution you need two intersecting lines.
But here only one line is given.
On a single line there lie infinite number of points.
So, for different values of x we get different values of y or different values of y we get different values of x.
So , we can write the above equation as
either ⇒y=9-2 x Or x=9-2 y
I have drawn graph for you.
Thus , there are infinite number of solution of this equation. Like (0,9),(1,7),(2,5),(-2,13),(-1,11),(-3,15)......
