Answer:

x =-2

Step-by-step explanation:

5x+1=2x-5

Subtract 2x from each side

5x-2x+1=2x-2x-5

3x+1 = -5

Subtract 1 from each side

3x+1-1 = -5-1

3x=-6

Divide by 3

3x/3 = -6/3

yarga [219]

Answer:

B. 5 + 2p

Step-by-step explanation:

<u>Let's simplify the problem:</u>

Joe has 5 + more than 2(P) as many calculators as John.

*We'll be using Addition and Multiplication operations.

If Joe has 5 more than 2 times the amount of calculators, the algebraic expression will be:

$5 + 2p$

p represents John's amount of calculators.

5 + (5 more than) 2(P) Twice the amount of calculators John has.
