Question

solve for x.\\(\frac{3.5x}{9} = \frac{4.2}{5}\\)\
enter your answer as a decimal in the box.\
x = \square

Explanation:

Step1: Cross-multiply to eliminate fractions

$3.5x \times 5 = 4.2 \times 9$

Step2: Calculate both sides of the equation

$17.5x = 37.8$

Step3: Isolate x by dividing both sides by 17.5

$x = \frac{37.8}{17.5}$

Answer:

$2.16$
