Question

x: (x + 4) = 3:5 Work out the value of x.​

Answer 1

Answer:

x = 6

Step-by-step explanation:

Expressing the ratio in fractional form

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

5x = 3(x + 4) ← distribute

5x = 3x + 12 ( subtract 3x from both sides )

2x = 12 ( divide both sides by 2 )

x = 6
