Answer:
Step-by-step explanation:
The given expressions are:
[tex]4x-y[/tex] and [tex]x+2y[/tex]
Now, we have to evaluate the expression using x=-1 and y=2, therefore by putting the values of x=-1 and y=2 in both the given expressions, we get:
[tex]4x-y=4(-1)-2=-4-2=-6[/tex]
and [tex]x+2y=(-1)+2(2)=-1+4=3[/tex]
which are the required solutions.
