solve the equation for y

4y+5x= -7

I came up with this is, is it right?

y=-5x/4+4

  • algebra -

    x+15=85

  • algebra -

    x + 15 = 85

    - 15 -15 (subtract 15 from both sides of equation to get x alone and keep equation equal.)
    x=70

  • algebra -

    4y + 5x = -7
    divide everything by 4 to get y alone
    4y/4 + 5x/4 = -7/4
    y + 5x/4 = -7/4
    subtract 5x/4 from both sides of equation
    y +5x/4 = -7/4
    -5x/4 -5x-4
    ________________
    y = -5x -7 / 4

    -5x - 7
    ___________
    4
