What is 15 times π

What is 15 times π

fifty point two four

What is 15 + 24?

39

14 divided by (14-x) equals 28 divided by (X-8)

14 divided by (14-x) equals 28 divided by (X-8)
28（14-x）=14（x-8）
392-28x=14x-112
-28x-14x=-112-392
-42x=-504
x=12

Can you tell me the solution of (28-x) divided by (14.5 + x)
one point five

（28-X）/（14.5+X）=1.5
==>28-x = 1.5 * (14.5 + x) ---- the left and right sides of the equation multiply by (14.5 + x) at the same time, and the equation remains unchanged
==>28-x = 1.5 * 14.5 + 1.5 * x --- distribution rate
==>28-1.5*14.5=2.5*x
==>x=6.25/2.5=2.5
