Evaluate the expression below when y = -3. 2y + 7 -4y - 10

Question

Need one asap been on this a week

Answer 1

You only need to plug it in and evaluate.

 

y = -3 so you have:

 

2y + 7 - 4y - 10

 

= 2(-3) + 7 - 4(-3) - 10

 

= -6 + 7 - (-12) - 10

 

= -6 + 7 + 12 - 10

 

= 3

Answer 2

Plug in -3 for y.
2(-3) + 7 - 4(-3) - 10

Simplify by evaluating the products.
-6 + 7 + 12 - 10

Simplify again by evaluating sums/differences.
