Question

If x=8 and y= -3, evaluate the following expression: 20- 5y+ 2x

Answer 1

21 is the answer you are looking for.

Explanation:

First, plug in the numbers for the variables:

`20-5(-3) + 2(8)`

Then use order of operations to solve, begin with parenthesis:

`20-15+16`

Subtract:

`5 +16`

Add:

`5+16=21`

So,

`20-5y+2x=21`

The correct answer is 21
