Question

What will be the result of substituting 2 for x in both expressions below? One-half x + 4 x + 6 minus one-half x minus 2

Answer 1

Answer:

12

Step-by-step explanation:

The equation is:

1/2x+4x+6-1/2x-2

Ok so you can cancel out 1/2x and 1/2x because 1/2x-1/2x=0

You are left with:

4x+4

If you plug in 2 for x

4(2)+4=12

I hope this helps :)

Answer 2

Answer:

Both expressions equal 5 when substituting 2 for x because the expressions are equivalent.

Explanation:

2 + 6 - 1/2 * 2-  2=5

and

1/2 * 2 + 4 =5

so both equals 5 :D
