Question

if three times a number added to 2 is divided by the number plus 5, the result is five halves, find the number

Answer 1

if I understand correctly, the equation should look like this:

\[\frac{ 3x + 2 }{ x + 5 } = \frac{ 5 }{ 2 }\]

now we multiply denominator of the left fraction with numerator of the right fraction and vice verse

\[(3x+2)*2=(x+5)*5\]\[6x + 4 = 5x + 25\]

from here on, it shouldn't be a problem; however, if you can't find the solution, feel free to ask;)

Answer 2

i cant find the solution =/

Answer 3

one more hint, put the unknowns to left side and known values to the right side of the = sign
