    D+Q=17
    or Q=17-D

    and 10D+25Q=275
    or 10D+25(17-D)=275
    solve for D, then solve for Q

  • math ALGEBRA 1 PLEASE HELP! -

    Distribute 25
    10D+425-25D=275
    Add like variables
    425-15D=275
    Subtract 425
    -15D=-150
    Divide Each Side by -15
    D=10
    Plug D into equation to solve for Q.
    Q=17-10
    Q=7
