How to find the number?</h3>
Let's define x as the number.
Now we want to write:
"the sum of 2/3 and for times a number...."
That can be written with the equation:
2/3 + 4*x
And we also know that:
"the sum of 2/3 and for times a number is equal to 5/6"
Then we can complete the linear equation:
2/3 + 4*x = 5/6
Now we need to solve it for x:
2/3 + 4x = 5/6
4x = 5/6 - 2/3
4x = 5/6 - 4/6
4x = 1/6
x = (1/4)*(1/6) = 1/24
x = 1/24
We conclude that the solution to the linear equation is x = 1/24.

H=x and b=x+10
A=hb/2 so
A=x(x+10)/2
A=(x^2+10x)/2 and A=48 so
(x^2+10x)=96
x^2+10x-96-0
x^2-6x+16x-96=0
x(x-6)+16(x-6)=0
(x+16)(x-6)=0, since x>0
x=6in, and since the base is x+10
base=16in
