  • algebra 1b -

    With first equation get x alone on one side.

    x = .5y - 2.5

    Substitute that value for x in the second equation and solve for y. Put that y value into the first equation to find value of x. To check, put both values into the second equation.

    I hope this helps a little more. Thanks for asking.
