Question

Solve for x: 5 over x equals 4 over quantity x plus 3 5 3 −3 −15

Answer 1

Answer:

x = - 15

Step-by-step explanation:

The equation is  $\frac{5}{x}=\frac{4}{x+3}$

We now cross mulitply and do algebra to figure the value of x (shown below):

$\frac{5}{x}=\frac{4}{x+3}\\5(x+3)=4(x)\\5x+15=4x\\5x-4x=-15\\x=-15$

Hence x = -15
