Question

Let x = -2 and y = 3. Evaluate 8x + 4y - 25

Answer 1

- 29

Explanation:

= 8x + 4y - 25

Sub in x = - 2 , y = 3

= 8 ( - 2 ) + 4 ( 3 ) - 25

= - 16 + 12 - 25

= - 29

Answer 2

-29

Explanation:

So we have the expression:

`8x+4y-25`

And we want to evaluate it for x=-2 and y=3. So, substitute:

`=8(-2)+4(3)-25`

Multiply:

`=-16+12-25`

Add:

`=-4-25`

Subtract:

`=-29`

And we're done!
