Question

Evaluate the expression

4x - y
x + 2y

If x = -1 and y = 2

Answer 1

The photo will show all work.

Answer 2

Explanation:

The given expressions are:

`4x-y` and
`x+2y`

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:

`4x-y=4(-1)-2=-4-2=-6`

and
`x+2y=(-1)+2(2)=-1+4=3`

which are the required solutions.
