Question 1061087
Pick an equation and solve for one variable in terms of the other.  Substitute this expression into the other equation and solve for the single variable.  Now use this found variable's value to evaluate the other variable.


You have two equations and two variables, so you have four ways to go.  Try to pick the way that seems easiest.


{{{y/2 -x=1}}}
{{{-x=1-y/2}}}
{{{x=-1(1-y/2)}}}
{{{x=y/2-1}}}
Substitute this for x in the OTHER equation.  Solve for the value of y.


Now do the other variable's evaluation.
