the units digit of a 2-digit number exceeds twice the tens digit by 1. find the number if the sum of its digits is 10.

Please help i am completley lost!!

  • algebra - ,

    x y
    y = 2x+1
    y = 10-x
    so
    10-x = 2x+1
    3 x = 9
    etc

  • algebra - ,

    im still pretty confused, but i think u r suppossed to solve the 2 equations u gave and got (3,7) but i think im way off

  • algebra - ,

    Check it by using 37 in the problem statement.

    the units digit (7) of a 2-digit number (37)exceeds twice the tens (2*3=6) digit by 1.(6+1=7 sure enough)) find the number if the sum of its digits is 10. (3+7=10 sure enough)

  • algebra - ,

    thank u
