Question

How do you evaluate `2x+3y+z` given x=-2, y=-3, z=5?

Answer 1

We just substitute the values of `x,y,z` in the expression and compute.

We have here, `x = -2, y = -3, z = 5`

Thus, our expression becomes,

`2x + 3y + z = 2(-2) + 3(-3) + 5`
`implies 2x + 3y + z = -4 -9 +5`

Finally, `2x + 3y + z = -8`
