Question

the equation is k+7 over x+1 equals 5 over 2if k=3 in the equation and x>0, what is the value of x?

Answer 1

x = 3

Step-by-step explanation

The equation is given as

`(k+7)/(x+1)=(5)/(2)`

If k = 3, then we are asked to solve for x.

`\begin{gathered} (3+7)/(x+1)=(5)/(2) \\ (10)/(x+1)=(5)/(2) \\ \text{Cross multiply} \\ 5(x+1)=2*10 \\ 5x+5=20 \\ \text{Subtract 5 from both sides} \\ 5x+5-5=20-5 \\ 5x=15 \\ \text{Divide both sides by 5} \\ (5x)/(5)=(15)/(5) \\ x=3 \end{gathered}`

Hope this Helps!!!
