Find the value of xhow do i find the value of it

We have similar triangles allowing us to form the proportion
x/(x+9) = 4/10

which is basically the ratios of the corresponding sides

Solve for x
x/(x+9) = 4/10
x*10 = 4*(x+9)
10x = 4x+36
10x-4x = 4x+36-4x
6x = 36
6x/6 = 36/6
x = 6

6

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
