    since the problem already tells you what Y equals just plug it into the 2nd equation

    \[\huge~\rm~3x-5=6x-8\] solve for x

    I think x=1 I'm just not sure about the right steps to find the answers

    yes perfect! :) Now we use that and plug that in place of X in the first equation \[\huge~\rm~Y=3(1)-5\]

    But it says I have to solve it by substitution or elimination and show all the steps. That's the part I'm confused about

    Wait never mind what you told me were the steps for substitution. Sorry!

    So would the next step be 3-5=6-8 ?

    Y=3(1) -5 3-5=6-8 3=6-3 6=6 X=1 Y=-2 Is that right???
