Question

3.4/2x−12 = 18/4.5 solve this by making proportion

Answer 1

3.4/2x-12=18/4.5
34/20(x-6)=180/45
(34×45)/20×18=x-6
(17×9)/2×18=x-6
17/4=x-6
17=4x-24
-4x=-24-17
x=41/4=10.25

Answer 2

The value of x is 6.425

Step-by-step explanation:

Given : $\frac{3.4}{2x-12} = \frac{18}{4.5}$

To find : The value of x

Solution :

$\frac{3.4}{2x-12} = \frac{18}{4.5}$

$3.4 \times 4.5 = 18 \times (2x-12)$

$15.3= 36x-216$

$15.3+216=36x$

$231.3=36x$

$\frac{231.3}{36}=x$

6.425=x

Hence the value of x is 6.425
