Answer
$x=0.25;y=0.625$
Work Step by Step
We need to isolate $y$ in the first equation.
$y=-0.5x+0.75$
Now, plug the value of $y$ into the second equation.
$1.25x-4.5 (-0.5x+0.75) =-2.5$
We get: $x=.25$
We will plug the value of $x$ into the expression of $y$ to find the value of $y$.
$y=-0.5(0.25)+0.75=0.625$
Thus, $x=0.25;y=0.625$
