can you help me with this equation and may you please show your work?

-3=3-y

  • math- pre algebra - ,

    -3=3-y
    You want the unknowns on one side and everything else on the other side. Let's move the 3 on the right side to the left side. We can do that by adding -3 to both sides.
    -3+(-3)=3+(-3)-y
    Remove the parentheses.
    -3-3=3-3-y
    Now combine terms.
    -6=-y
    Now multiply both sides by -1 to get rid of the minus signs (we want to know y, not -y).
    -1*-6=-1*-y
    6=y or if you prefer
    y=6
    check my work.
