Three times the sum of a number and 2 is the same as three-fifths of the sum of the same number and 22.what is the number?
Let
x -----> the number
so
Three times the sum of a number and 2 -------> 3*(x+2)
three-fifths of the sum of the same number and 22 -----> (3/5)*(x+22)
therefore
3*(x+2)=(3/5)*(x+22)
solve for x
5*(x+2)=x+22
5x+10=x+22
5x-x=22-10
4x=12
x=3
