Answer: x=5
Explanation:
(3x)/5=(x+1)/2
As the problem instructs, multiply the numerator of one factor by the denominator of the other. Just imagine lines making an X connecting what needs to be multiplied with one line per equation
3x*2=6x
5*(x+1)=5x+5
then simplify and you get
6x=5x+5
Then solve normally, subtract 5x from each side
6x-5x=x 5x-5x=0
x=5
