Question

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

Answer 1

51

Explanation:

Given the following question:


`20-5y+2x`

`x=8`

`y=-3`

Substitute and solve using PEMDAS:


`20-5y+2x`

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

`5*-3=-15`

`20--15+2(8)`

`2*8=16`

`20-(-15)+16`

`20--15=35`

`35+16=51`

`=51`

Your answer is "51."

Hope this helps.
